Live Rock and live sand for Your Saltwater Aquarium

new live rock

If you are in the process of setting up a saltwater aquarium in your home and wondering about what live rock and sand are, and how to incorporate it into your tank, you will find all the answers below.

What is Live Rock?

Live rock comes from the ocean and is made up of the aragonite skeletons of corals that have long since died, and other calcareous organisms. When live rock comes from the ocean, it is usually inhabited by a variety of marine life, hence the name “live Rock”. Live rock is harvested from the sea for the aquarium trade and is not only necessary, but also adds to the décor of your tank, making it visually appealing.

Live rock needs to be cured before it is placed in your aquarium. Most of the organisms that did live in the rock before being taken out of the ocean, would have already died, which can pose a risk to a new aquarium. To avoid this problem, the rock gets put into water for a few weeks, making sure that all the dead organisms decompose completely. This process is needed so that the rock can no longer be a threat to the water quality.
There are a variety of different kinds of live rock, which get their names from the area where they came from. Each different type has different qualities that work better in certain kinds of aquariums.

Types of Live Rock Available for Hobbyists

There are many different types of live rock available. Which type you choose to use is a personal choice. Here are the names of the variety of live rock available for your reference:
Fiji live rock, Totoka live rock, Florida rock, Caribbean rock, Vanuatu rock, Tonga rock, Base rock, Pacific rock, Atlantic rock, Reef rock, Cultured rock, Base rock, Artificial rock, Cured rock, Uncured rock, Eco-rock, Tonga rock and Aqua-Cultured Rock

What is Base Rock?

Base rock is a dry rock that never had any organisms living on or in it. Base rock is generally used as a filler for your aquarium and is much cheaper than live rock. It can also be hand-made from concrete called aragocrete. Hand-made base rock tends to be less attractive and heavier than natural rock that was harvested from the ocean.

How to Cure Live Rock

There are a number of different ways to cure live rock, but here are two methods that are recommended. Although it is not necessary for you to do this, as already cured live rock can be bought, if you wish to cure it yourself, here is how to go about it.

Method 1

This is the process to follow for aquariums that already contain corals, fish and other marine life.
Rinse each and every piece in a container of saltwater. This is done to remove debris, sand and other loose matter.
Using a new 30-gallon plastic container, put the live rock into the container and add seawater (gravity 1.021-1.025), making sure the rock is completely submerged.

Use a heater to keep the temperature of the water between 76 and 84 degree F. The warmer the water is, the faster the process will be completed.

Use an air stone or power head to create constant movement in the water.
It is important that you keep the area dimly lit because this prevents algae blooms.
You need to change the water every week – 100%of the water!
The rock will need to be scrubbed. Use a toothbrush or other nylon bristled brush. This needs to be done every time you change the water. Scrubbing the rock removes any dead materials.
After a week, you must periodically check the nitrate and ammonia levels. The rock is considered to be cured when the ammonia level tests reveal zero and when the water has stabilized. Once you reach this stage, your rock is ready to be put into your aquarium. It usually takes between 3 and 5 weeks for rock to be fully cured with this method.

Method 2

This is the process used for curing rock for an aquarium that had NO coral, fish or other marine life.
Live rock can be used in new aquariums. Firstly, you need to follow the directions provided by the manufacturer with regards to the installation of the filtration system and all other accessories. Fill your new aquarium with water and enough salt to get the correct water gravity (1.021-1.025). One that has been done, activate all the equipment, check to see if there are any leaks and then set the chiller/heater to between 76 and 84 degrees F.

As with method 1, rinse all the rock in a container to free it from all debris, sand and other organic materials.
Put the rock directly into the aquarium, creating a stable base for decorations and corals.
In order to reduce the possibility of algae grow, it is important to remember to keep the lighting system off during this time.

The rock will need to be scrubbed. Use a toothbrush or other nylon bristled brush. This needs to be done every time you change the water. Scrubbing the rock removes any dead materials.
The water will need to be changed (50%) on a weekly basis. This is done by siphoning out loose debris and other organic matter that has accumulated in the aquarium.

As with method 1, the nitrate and ammonia levels need to be checked on a weekly basis.
When the levels of the ammonia and nitrate are at zero, you need to perform a water change (50%).
Check the pH level of the water after 24 hours and adjust accordingly. The correct level is between 8.1 and 8.4.
With this method, most aquariums will be ready in 3-5 weeks.

How to Control Unwanted Pests

Place new rock into a container filled with saltwater (gravity 1.035-1.040) for one minute. Any bristle worms, mantis shrimp and crabs will very quickly leave the rock and end up in the water.

After the minute, take the rock out of the container and go through the invertebrates that are left behind. There may be some that you actually want in your system, so sort through them and get rid of the pests that you do not want to add to your aquarium. Bristle worms tend to stay attached to the rock, but you an easily remove them with a tweezers or a needle-nosed pliers. You can use this process before or after your rock is cured.

What is Live Sand?

newly laid live sand

Getting a new saltwater tank ready for the first few animals can be a challenging task. It can take some time to build a solid base for a successful aquarium.

Live Sand Explained

Basically, live sand is sand that a variety of invertebrates and bacteria call home. The sand is like an organ to an aquarium, much like the kidneys are to the human body. The kidneys take away pollutants and replace them with not so toxic chemicals that your body can deal with, which is what the sand does for your tank.

Live sand is a place where your tank’s “clean-up” team grow and live. Copepods, bristle worms, mini starfish and other marine creatures all live in and around the sand. They are all important for the health of your tank. They keep your tank clean.

When you buy live sand from a fish store, it is already inhabited by the invertebrates and bacteria that are needed to keep your aquarium healthy and clean.

Do I Have to Use Live Sand in my Tank?

It is not necessary to use live sand in your tank. Some people opt for not using any sand at all. Any sand that you add to your tank will become live sand after a while. Buying live sand can be a lot more costly than dry sand and comes in smaller bags as well. You do not need to buy live sand, as you are able to add dry sand that has just been washed, but make sure it has not been treated with any chemicals.To the sand you could add a little live sand which will spread into other sand creating a tank full of live sand.

You will need to boost your biological filter in some way, but if you are adding live rock to your tank, that will be the cultural boost that it needs and any sand that is present will become “live sand”.

The “Cheap” Method

It is recommended that you use regular sand in your tank if you are working on a strict budget. Live sand might work faster, but dry sand will work just as well, only it will take a little longer to see results. Adding just a small amount of live sand to regular sand will give it the boost it needs. The bacteria and other living creatures in the live sand will move into the dry sand and eventually make it become live sand.

How to Choose a Product

There are so many different options available, so how do you choose the right one for you. It is pretty simple actually you should choose a product according to how you want your tank to look. CaribSea is a popular choice for many people. You will also need to think about the types of animals that will be in your tank. Are they going to burrow in the sand? If so, you will need a specific type of sand.

The Benefits of Using Live Sand

It starts the cycling process right away.
Helps to maintain the correct pH levels.
It provides shelter for fish who like to bury themselves and a place for invertebrates to hide.
It lowers the levels of harmful nitrate
Essentially, at the end of the day, the live rock and live sand that you choose to use is a personal choice. Consider all your options and speak to the staff at the store for further advice on how to achieve what you are looking to create with your unique aquarium.

What You Should Know about feeding your koi

Having a pond might be a good idea, especially one that’ll be booming with life. However, you can’t ignore having to feed your koi with proper koi food. With koi being a popular choice for any pond, what most people don’t realize is that they need to be fed regularly. Thinking that your koi will find enough food to eat from the wild in the pond is wrong. You’ll need to make an effort to feed them.

 

Everything you need to know to properly feeding koi is set out below.

Koi belong to the carp family, which means that they are omnivorous and can eat various kinds of food. However, feeding your koi involves more than just the food they eat. Here is a guideline of how much, when, and what to feed your koi.

Factors affecting feeding koi

There are various factors that you should take into consideration when feeding koi. You can’t just throw food in the pond thinking that your beautiful fish will eat it when hungry. You need to be aware of the food quality you’re giving, the temperature of the water, and the overall environment of the pond among other factors.

1. Food quality

The quality of food that you give to your koi plays a vital role in the rate of their growth as well as their well-being. This means that feeding your fish, food that isn’t high-quality will eventually make them ill. On the other hand, giving koi good quality food of , which a lot of pets shops have available, will have a positive effect on not only their body weight but also on the color and vibrancy of your fish.

Which foods are suitable?

Koi welcome various kinds of live foods which include worms as well. You can easily feed earthworms to your koi throughout the year. Worms contain a high amount of protein and are a favorite of omnivorous fish. You can also go green when feeding koi.

These ornamental fish will eat lettuce leaves as well as the flora present in and around the pond, such as duckweed.
You might want to throw other food to them such as pieces of bread. Koi will usually eat most types of food thrown in the pond to them; However, most of these food have little or no nutritional value for them and may even harm your fish.

You can feed your fish brown bread but not white. White bread is made using mild bleach; So do not feed your koi white bread.

Koi also eat foods like corn, beans or peas which have a shell-like skin. However, this skin will lead to your fish experiencing irritation as digesting the shell is difficult for them.

2. Temperature of the water

The water temperature determines the amount of food your fish eats as well as the frequency with which it eats. If you try to feed koi during winter, when the temperature of the pond is low, at the same rate with which you fed them during the warm summer months, you’ll end up harming them.

The digestive system of koi is dependent on the temperature of the water they live in. In cold temperatures, their digestive system slows down and even stops when the water is cold enough.

As the temperature of the water starts to fall, the level of protein that you mix in the feed should also be reduced. This change will not only help to make digestion easier for your koi, but will also help to avoid waste.
Similarly, as summer arrives and the temperature of the pond starts to increase, the protein in the feed should be increased because the metabolic rate of your koi will speed up. Therefore, a higher amount of protein will be needed for proper growth as well as for maintaining their health.

As mentioned, the temperature of water not only governs the kind of feed that one should use, but also the frequency at which the fish should be fed. When the temperature is low, feeding koi only once a day will be enough. On the other hand, when the pond’s temperature rises, koi can be given food every hour.

How much should you feed?

Of course, the amount of food as well as how often koi should be fed is debatable. However, a general rule is that when the water is around 58-Farenheit or below, then the protein level of your feed should be below 38%. When the water temperature falls below 46-Fahrenheit, you should stop feeding altogether.
Similarly, as the temperature of water rises, the amount of protein in the food, as well as the number of times you feed your fish in a day, should be increased. During the high-temperature summer months, the amount of protein in your feed should be somewhere in the forties and the number of times you feed the koi can rise to eight times per day.

Keep in mind that the fish should only be fed for a maximum of five minutes per one feeding. In the case where the fish doesn’t come up to devour the food, then this is an indication that the fish is either too warm, too cold or are not feeling hungry for some reason.

So, make sure that you feed light. If your fish are eating like they haven’t been fed for years, then you can just sprinkle food lightly on the water for a few minutes as long as you can see fish coming up to eat the food.

3. Quality of water

The quality of water has an effect on the growth rate of your koi, because in poor water quality your fish may lose their appetite and won’t eat the food provided. They might even stop feeding altogether. Moreover, poor quality of water negatively affects the metabolic rates of koi, hindering their digestion process.

Furthermore, the stocking level, which is the amount of koi you have in the pond, also affects the behavior of the fish and the way it grows. This means that you should have such an efficient filtration system which can easily cope with the increased amount of waste produced as your fish continue to eat and grow.

If your filtration system is not sufficient for the number of fish in the pond, then the quality of water will be significantly affected, which in turn affects the amount of food that the koi takes in.

More factors you need to consider

There are two more things you need to take care of when feeding koi. One is the digestive system of the fish and the second is overfeeding.

Digestive process of koi

The gut system of koi is a very simple one. They only have a long straight intestine through which all their food passes. The nutrients are extracted from the consumed food when it passes through their intestine. Therefore, your koi can only digest a small amount of food at a time. The amount decreases even more as the temperature of the water decreases.

Therefore, it is vital that you feed fish the right amount of food and a sufficient amount of protein to make sure that they extract the maximum nutrition from the food while also avoiding the possibility of over feeding.
Overfeeding

Perhaps, overfeeding is the most common mistake people make when it comes to feeding koi. One reason behind this is the fact that feeding time is the most enjoyable time that you have with your koi. During feeding, the koi come towards the surface to eat. At this time, you can not only see them eat, but can also interact with them. Seeing your fish gather near you while you feed them can make for an enjoyable experience. And they will become tame to you through continued feeding.

Overfeeding refers to any period where the fish eat more than the amount of food they require. This has adverse effects on your fish. An excessive amount of food can lead your fish to become sick and the increased amount of waste that the koi would have to produce causes the quality of water to decline exponentially.

Moreover, if the fish in your pond are fed an increased amount of food, then they develop huge pot bellies, and they start to resemble tadpoles because of their wispy tail and big body. Of course, this does not kill the koi; however, it does severely affect the internal organs such as the liver, and the natural beauty of these creatures.

When you feed more food than your koi can eat then this will stay in the water and pollute the water causing pollution which may make your koi ill. If you can remove any uneaten bits of food five minutes after feeding then you will save your fish any stress from rotting fish food.

Want to feed your koi from your hand?

Koi can enthusiastically learn to eat out of your hand. Once the fish get used to the idea of you being close to them, then you can bring some koi cookies or bread as a treat in an attempt to bring them even closer to you. You only need to dangle your hand filled with tasty treats in the water for them to come to your hand.

However, this task takes time before your koi become tame enough. It may take weeks or months before one of your brave koi to make its way towards you to enjoy the treat from your hand. It will take further time for the others to catch on to the same routine. Soon, the other koi will also be swarming towards your hand in search of the delicious treat.

If you take it slow, the koi might be able to be okay with an affectionate rub and even a pat on their head! That is how tame koi can become. And they may even just come to your hand even when you don’t have food for them.

Top 10 tips on African Cichlids

crowded malawis

Top 10 tips for a successful African cichlid tank

African cichlids on youtubeTip number one. Watch a lot of cichlid videos on youtube. With many expert hobbyists giving first hand experience of setting up a cichlid aquarium, which species to buy, maintenance of a cichlid aquarium through to breeding the various, mbunas, peacocks, haps, Tanganyikans and other topics. Always be prepared to learn more because there’s tons of information in video format.

Tip number two. Over filtrate. Always buy a filter that is twice as powerful as the recommended size. Your tank has to be super clean the reason is because most Malawi tanks are overcrowded. Malawi aquariums are over stocked to spread aggression. Malawis are big eaters and cichlids are constantly producing waste you need to over filtrate. Running two filters simultaneously in the same tank is also a great idea. Canister filters are a must. You need to stuff them full of good filter material to do both mechanical and biological filtration.

Tip number three. Overstock your tank. Overstocking will crowded malawishelp spread the aggression between the fish so that no individual fish gets singled out. Even then you will still see aggression, where one fish will want to eliminate another particular tank mate. It is something that you have to expect when keeping Africans. But do all you can to keep that kind of behaviour down. To reduce it to a minimum. over stocking your tank, rearrange the rock scape every two weeks, and be quick to act when you see one fish getting constantly bullied by another. If it looks like one fish has picked out another fish for destruction remove the aggressor or the victim immediately.

Tip number four. Act quickly when you see a fish getting beaten up or looking ill. If you see mouth locking, tattered fins or hit marks on the side of the body. Immediately remove the weak or injured fish. If you leave it too late and remove a harassed fish you will often find that the fish will still end up dying either the same day or a few days later.

yellow bags in bagTip number five. Always add 4 or more fish to an aquarium at a time. Adding just one or two fish to an established aquarium results in the new fish entering other fishes already established territories and so will get beaten up.

Tip number six. Spend less on the filter canister and use the money saved to buy good quality filter media. And again having two canisters will enable you to service one canister while the other keeps running doing its job of filtering the impurities from the water and avoiding ammonia and nitrite spikes. And if
one filter fails you will still have one filter running until you can fix the broken filter or buy another one.

Tip number seven. If you skip one day a week of feeding the fish or possibly two days a week you will notice that your fish are more healthy and active. Also they will be less prone to getting Malawi bloat which is common in Malawis which are always eating. They are supposed to be eating mostly algae. So when they eat dried foods which are a more concentrated food than they find in the wild, you are actually overfeeding them. Also the water will be cleaner because less eating results in less fish waste.

Aquarium water changeTip number eight. Change 40-50% water changes every week. Try and set up an automatic top up system. Use a long hose system of some sort. When you add tap water use a water conditioner. It is wise to overdose rather than underdose on water conditioner. The easier this task is the less likely you are to skip it. Carrying buckets of water up and down in your living room every time you do a water change is likely to cause an accident at some time.

Tip number nine. Research on YouTube on the particular species of African that you intend to buy. You need to find out whether your particular fish is overly aggressive or passive or even a carnivore. Or the fish may grow much bigger than you can cope with. Always be prepared to move on a fish that is not suitable for your aquarium. Some fish that are beautiful and small when young can become nasty monsters that quickly outgrow your aqurium.

sulphur head peacockTip number ten. Don’t be too obsessive over getting everything exactly right. This is a hobby that is meant to be enjoyed so relax and don’t be too worry if the tank is not too perfect. You don’t have to be overly precise. Remember Malawis are strong fish that are mostly immune to things like ich.

Lastly an overall tip is to always chat with other hobbyists on the forums. Ask questions. Answer other people’s questions. Share your experiences with other hobbyists.

Common livebearer illnesses: how to recognise and treat them

Common livebearer illnesses

livebearers facts and info

How to maintain healthy livebearers

Most tank raised livebearers are quite healthy fish. In other words they hardly ever get sick as long as their aquarum is kept clean and healthy and nothing goes wrong such as a faulty heater.
However, dirty water, overcrowded aquariums, overfeeding or even a poor diet can lead to livebearers getting sick.

Diseases can be avoided and should be avoided rather than relying on medications and treatments to cure sick fish it is better to avoid the conditions that lead to sick fish.

Here are some common sense tips:

  1. Don’t buy sick fish. Even apparently healthy fish should be quarantined for a few weeks in case of hidden illnesses to avoid spreading illness to your existing fish.
  2. Remove dead fish immediately. I dead fish which may have been carrying an illness will release its illness into the water as it decomposes. Also a decomposing fish will rot and pollute the water causing the other fish harm. A partial water change after removing a dead fish is a good idea too.
  3. Check your fish daily for any signs of lack of health such as lethargy, clamped fins, scratching against objects or unusual breathing by the fish.
  4. Treat your fish as soon as a disease is spotted. Some diseases can only be cured if the disease is treated early.
  5. Keep common fish medications at hand. In other words buy them early. Methylene blue, malachite green, white spot medication and an antifungal medication are helpful first aid. Also sea salt is often helpful.

Common illnesses that affect livebearers

1) White spot
The signs of white spot are white dust like spots about the size of a grain of salt sprinkled over the body and fins of affected fish.
Treat fish early. Fish can die from untreated white spot. Raise the temperature to 85F but less for livebearers from cooler waters. Add some salt to the water. 1 teaspoon per 5 litres of water. Treat with the latest white spot medication as well.

2) Mouth fungus (cottonmouth)
Recognised by white fluffy growths around the mouth or occasionally along the fins. Although it looks like fungus, it is not. It is actually caused by a bacterial infection – columnaris.
Treat fish with marycin, salt added to the water and malachite green. Cottonmout has become resistant to some antibiotics so you might have to re-treat with a different antibiotic.

3) Fin Rot
Signs of fin rot are split or frayed edges to the fins with dark or white edging to the fins.
Treat with nitrofurazone or a similar wide spectrum antibiotic. Also add salt and methylene blue to the water.

4) Fish tuberculosis
Symptoms include bloated stomachs, pop-eyes, body abscesses and protruding scales.
This is very difficult to treat because TB forms a protective mass coating that prevents antibiotic penetrating to kill off the bacteria. Very sick fish are best killed.

5) Gill flukes
Symptoms include: fish having laboured breathing with gill covers open. Fish may also start scraping their gill plates against objects.
Treat with praziquantel baths. Alternatively treat with a dylox bath.

6) Intestinal parasites or worms
Symptoms are thin bellied fish, stringy white poop. Fish may go off their food.
Buy anti-parasitic medication that can be mixed into the fish’s food. If the fish are not eating you will have to capture the fish and inject the medication directly into the fish’s mouth.

7) Cloudy Skin
Slimy looking film on the skin or fins is an infection of ciliates or flagellates. This may be cured by raising the temperature slowly over several days until it reaches 85F and treating with methylene blue.

8) Poisoning
The fish will have clamped fins and may dart about the tank and rub against objects. Fish will also breathe heavily.
The main causes of water poisoning are Chlorine from tap water, ammonia from decaying organic matter or a build up of fish urine and poop, chemicals from aerosol sprays, insecticides such as fly killers are pretty bad.

Do an immediate 50% water change with safe water that has been standing for at least 24 hours and is the same temperature as your aquarium. Remove any decaying matter or dirt in the aquarium, remove excess mulm from filters, stop feeding. After 24 hours do another 50% water change.

9) Fungal infections
Symptoms are white or greyish fluffy patches on the body or the fins. This may come about from injury to the body or fin. Dab the affected area with cotton wool dipped in malachite green or set up a malachite green bath dip for the fish. Leave the fish in the bath for 1 hour.

10) Shimmies or livebearer disease
Symptoms are when your fish continually rock from side to side.
This is thought to be because many livebearers prefer hard alkaline water with some salt added. Livebearers kept in soft acidic water will over time develop this disease.
Treat by adding some salt to the aquarium and find ways of adjusting the ph and hardness of the water. Perhaps by the use of crush coral sand or dolomite sand.

 

Feeding guppies, mollies, platies and other livebearers

guppies and platies in a community tank

Feeding guppies, mollies, platies and other livebearers

Make your own fish food

Raising live food

Feeding livebearers can be easy especially the commonly found livebearers, but to get the best results then care must be taken with their diet. Most livebearers are omnivorous, eating both animal matter and vegetable matter. Other livebearers are mostly vegetarian such as the platy and goodeid livebearer. And the last group of livebearers are carnivores that need live food and even small fish to eat such as pike livebearer, half beaks, four-eyed fish and porthole livebearer.

Dried food forms a livebearers staple diet

Dried foods can be used to feed most livebearers but if you have vegetarian livebearers or carnivorous livebearers then you need to pick a brand that has a high vegetable content or high protein content. Supplement dried foods with live food at least once a week. And for the vegetarian livebearers add some sliced vegetable matter such as a cucumber slice.

The biggest problem with dried food are that they quickly become stale. So it is best to buy only small quantities at a time and when you buy them check the sell by date and whether the carton looks dusty. Do not buy old stock.

Dried foods come in several varieties. Food flakes are the most common and are a good choice for livebearers because the flakes float giving the livebearers a chance to eat from the surface. Most livebearers are surface feeders.

Types of dried foods for livebearers

Food flakes come in different sizes. The sizes are there to allow you to feed fish with small mouths or fish with large mouths. If there are fry in the aquarium the just crumble a few flakes into crumbs for them.

You could also feed fish pellets to your livebearers. Care must be taken to buy a brand that has floating pellets. Livebearers will usually ignore food that has fallen to the floor of the aquarium where it will rot and pollute the aquarium. The advantage of pellets is that they are less processed than flakes and are just compacted bits of dried food.

Food tablets are useful if you will be away for days at a time. They are compressed food tablets that dissolve slowly over sevearl days. The fish will pick off bits at a time and will be kept fed while you are away.

Feed live food to keep your livebearers healthy

All livebearers benefit from the occasional meal of live food. The fresh vitamins, minerals and amino acids available in live food can not be obtained from dried foods. Once or twice a week is sufficient for most species. But for vegetarians you will also need to feed fresh vegetable matter at least once or twice a week.

Live food can also come in the form of frozen live food and freezze dried food. These are not quite as nutritiuos as real live food.

Where can you obtain live food?

  1. You can keep a large 200l litre barrel of water in a sunny spot in the garden. This will attract mosquito larvae and blood worms. But you can also seed the barrel with daphnia. Daphnia needs to be fed daily with green water or yeast powder. This is the safest and best way of collecting live food for your fish.
  2. You can buy live food from the pet store. But care must be taken to examine the bags of live food for freshness. Some bags of live food can be full of dead insects which is a waste of time. Also some pet shops will sell live food which may contain illnesses from their fish or other source, even the best aquarium store may be quilty of this.
  3. You can collect from wild sources. Good sources for daphnia are from water troughs for cattle or horses and are generally safe. Collecting from wild ponds is a danger. Care must be taken not to collect parasites and other nasties alongside your chosen live food. Best to avoid any pond that contains fish.
  4. You could also raise live food such as brine shrimp to adult hood to feed adult fish. Brineshrimp is an excellent choice of live food except for the effort you need to put in to raise the shrimps. You can also raise white worms or fruit flies. All make a nutritious supplement to dried foods.
  5. Another excellent choice is small earthworms. You will need to rinse out any soil from the worms stomach. Chop the worms up with a razor into small pieces to feed your fish.

Best live foods include daphnia, cyclops, mosquito larvae, and even earth worms, white worms and fruit flies. If you can give your fish a variety of live food as well as some vegetable matter then all the better for the health of your livebearers.

Vegetable items to feed livebearers

A slice of cucumber, boiled spinach or lettuce leaves, spirulina and algae are a good source of vegetable matter for livebearers. There are many vegetable items that can be chopped up into small pieces and fed to your fish. Experiment with what your fish will eat. Try ensure that the items float. Tie a cotton thread to the vegetable piece to keep it near the surface. Also after a couple of hours remove any uneaten vegetable item and throw it away.

Variety in feeding keeps your livebearers healthy and breeding

If you bear all this information in mind and feed your fish using this knowledge then your fish should remain healthy, vibrant and active. Remember variety is the spice of life and it goes for the food of livebearers too. They will of course reproduce when fed well which is a sure sign that they are healthy.

Maintaining a healthy livebearer aquarium

The secret to keeping healthy livebearers is in keeping the water they live in healthy and suitable for them to live in. The major element in maintaining healthy water is the continuous removal of pollution from the water.

Where does aquarium pollution come from?

Pollution in the livebearer aquarium comes from the fish themselves. Livebearers are continually producing urine and occasionally pooping in their own environment. Also pollution can come from any uneaten food left to rot in the aquarium. Occasionally from the rotting of a dead fish or other water borne creature can cause pollution as well as dead plant material.

You can certainly remove much of the pollutants from the water by siphoning them away and disposing of it. However there is much that will be missed and so you need a filter to remove the remaining pollutants.

A much better automated way of cleaning the fish waste is by relying on biological filtration known as cycling.

Maintaining the correct environment for a livebearer aquarium

Besides keeping the water clean, to maintain a healthy livebearer aquarium you need to maintain temperature control and provide lighting as well as providing suitable water conditions.

Electrical safety in a livebearer aquarium

Most of the equipment used to maintain a healthy livebearer aquarium is powered by electricity. And as you may well know electricity and water make a dangerous combination. So, you must observe certain electrical safety rules as follows:

  1. Only buy and use electrically certified equipment from a recognised aquarist supplier
  2. Buy a safety cut out cable that will cut all electricity to the aquarium when there is a fault.
  3. Unplug all electrical devices in your aquarium when you are working inside the aquarium water or you risk electrical shock. Don’t forget to turn it all on afterwards.

Livebearer fish tank selection

hawaii-platy-variatusThe first thing you need to buy when keeping livebearers is a fish tank. This ideally should be an all glass aquarium bonded together with silicone. Plastic aquariums although lighter are easily scratched and ruin the view of your fish.

Fish need a good supply of dissolved oxygen in the water to breathe. This oxygen comes through the surface of the water. The area of the surface of the water determines how much oxygen will be available for your fish’s use. In other words, the larger the area, the more oxygen and so allowing you to keep more livebearers. Measure about 5 litres of water for every fish as a bare minimum. A 100 litre tank should allow you to keep up to 20 livebearers.

Remember that water in large aquariums can be very heavy and must be placed on a solid floor that can support the weight. If the floor is concrete then it should be fine. However with floor boards you will have to find out where the supporting joists are underneath the floorboards and place your stand on top.

Because livebearers are surface swimmers they tend to be jumpers. This means that livebearers occasionally make a leap to freedom and can end up dead on your living room carpet. So, you need to buy a tight fitting lid to prevent this.

Filtration in the livebearer aquarium

mickey-mouse-platyThe most important piece of equipment in eliminating pollution in your aquarium is the filter.

Sponge filters

A surprisingly good and effective filtration system is the sponge filter powered by an air pump. Sponge filters are not very powerful but you can use 2 or 3 of them together in the one aquarium. A great advantage of the sponge filter is that they are low maintenance and also they are cheap to buy. All you need to do to clean them is to squeeze them out in a bucket of aquarium water and then swirl them about until most of the excess dirt falls off. Do not remove all the dirt as the biological bacteria that filter the fish waste live in the dirt. Removing the excess dirt will unclog the filter and allow this bacteria to breathe and grow.

Contrary to popular belief, the most important job a filter has to do is not to remove particles and dirt from the water. No, the most important job of a filter is provide a breeding ground for bacteria that break down decaying organic matter into harmless substances.

It takes between 4-6 weeks for the bacteria in a filter to mature to the level where it can remove all the decaying pollution effectively. It is very important that you take care to not kill off the bacteria in the filter. Washing the filter in tap water that contains chlorine will kill the bacteria. Certain medications can also kill of the bacteria. And finally turning off your filter for more than an hour can kill off most of the bacteria in your filter.

Box filters

Box filters can also be used to filter the aquarium water. These are more powerful but cost more than a sponge filter. They may contain an internal sponge too. The disadvantage is that they are difficult to clean and maintain.

External filters

There are even more expensive and powerful external filters that may hang off the back of the aquarium. These may use various filtering material.

All filters ultimately rely on the same method to filter and that is by passing water over a colony of bacteria that have grown inside the mulm that has collected in the filter.

Other methods of removing waste

Despite filters doing such a marvellous job of biologically breaking down waste matter into less harmful waste products, you still need to do some clean up yourself. At least once a week you will have to use a siphon device to sift through the gravel stirring the dirt up to be siphoned into a bucket and thrown away. Siphon away any dead plant material as well.

Uneaten food should be siphoned five minutes after feeding. Dead fish and other creatures should be removed as soon as seen.

Lighting is another important piece of equipment.

Livebearers enjoy bright lighting conditions. However, bright lighting may encourage excessive algae (which is microscopic plant life). Algae is usually healthy for your livebearers who will eat it, but it is an eyesore and may choke off your plants.

The solutions to prevent or remove algae is to keep your aquarium away from direct sunlight and also to reduce the number of hours per day your aquarium lighting is on for.

There are 3 types of bulb that you might use in your livebearer aquarium.
a) incandescent bulbs
b) fluorescent tubes
c) Mercury vapor lamps

Incandescent light bulbs (ie home light bulbs) can be used in fry rearing tanks and quarantine tanks. For most aquariums you should use fluroescent tubes that are widely available and inexpensive. Although expensive, mercury vapor lamps can be economical in very large aquariums where 1 vapor lamp bulb would replace many fluorescent tubes. Vapor lamps are very bright. One vapor lamps is 4 times brighter than a fluoresent tube.

Gravel or sand? The choice is yours.

If you use gravel then you can put plants directly into the gravel with a tablet fertiliser pushed in near the roots. The gravel should be 2 inches deep.

Sand is not so good for plants because it is too compact. Sand may also trap dirt and compact creating stagnant “dead-spots” that may foul the water. To lessen this risk use a shallow layer of 1 inch or less. It is recommended that you place plants in their own little plant pots above the sand.

In the wild livebearers swim in waters where the base is light coloured, so sand is quite comforting for them. You could also buy a light coloured gravel. The lighter coloured base brings out the best in your livebearer’s colours.

Before using gravel or sand in your aquarium you must rinse out dust by placing some sand or gravel a bit at a time in a bucket and running tap water through while swirling it with your hands until the water runs clear.

Plants for a livebearer aquarium

Thriving plants remove the waste products created by the fish. Indeed the plants feed off the decomposed fish waste matter.
Plants also add visual naturalness to an aquarium that is comforting to the fish. The plants create hiding places for females and young livebearers. And finally plants also provide a source of fresh food for your ever hungry livebearers.

Choose plants that like your tap water’s composition in terms of ph and hardness and are hardy aquarium plants. Plants such as Java moss, Java ferns, Cryptocorynes and vallisneria are ideal choices for livebearer aquariums.

What is the correct conditions for livebearers?

Not only do you have to maintain clean water for your aquarium, you also have to provide water of the right composition. Tap water is normally within range of suitability for livebearers. The main factors in water composition are ph level and hardness level of water which can be tested using a test kit bought from your aquarium store. If your tap water has a reading of ph 6.5-8.4 and the hardness reading is above 8dh then that should be acceptable for most livebearers. If the ph and hardness fall out of this range then you need to perform the laborious process of adjusting the water condition. This is best done by having a 200litre barrel and preparing large batches of water at a time.

What exactly is harmful about fish waste? When fish poop and urinate where does this go? What happens to it?

When fish poop and urinate this waste matter decomposes slowly releasing ammonia, which is quite poisonous. In a mature aquarium with a mature filter bacteria breaks down this ammonia into nitrite. In a new aquarium with no bacteria this ammonia builds up and slowly poisons the fish.

How to create a mature filter – cycling.

Nitrite is also poisonous but a second set of bacteria digest nitrite and convert it into nitrate which is relatively harmless. Nitrate is absorbed by plants as a fertiliser.

With this in mind it is essential to buy and use a test kit that measures ammonia and nitrite levels in a new aquarium. You will need to check the ammonia and nitrite daily until they come down to 0.0. In a new aquarium you will have to do daily water changes of between 10-20%. This will reduce the pollutant levels. You have to carry on the daily water changes until the readings hit 0.0 at which point your filter’s bacteria will be mature enough to cope. If you get a particularly high reading during this process do a bigger water change and stop feeding for a day or two.

With all this new found knowledge you should now be in a position to keep your livebearer aquarium healthy in the long term.

Fish adaptation in the wild

Fish adaption in the wild

Fish as a group are one of nature’s success stories. Fish can be found in nearly all bodies of water and on occasion can be found flopping onto land. Even the most inhospitable bodies of water such as suphurous thermal springs, ponds that dry up in summer, the deepest part of the ocean have all been colonised by fish.

It is estimated that there are currently 30,000 different species of fish on earth. That is more than any other vertebrate. There are thousands of species that live in freshwater tropical streams, rivers, ponds and lakes. The most abundant of these are in Africa, Asia and the Americas.

The most popular species of fish from these bodies of water have found their way into the aquarium trade and into people’s homes the world over. The most popular species in the hobby are usually the most colourful, hardy and easiest to breed or they may have an unusual shape or unusual behaviour.
Adapting to life

Fish have been on earth longer than reptiles, amphibians, birds and mammals, all of which have evolved from fish. It shouldn’t come as a surprise to note that fish have had longer to adapt to their environment than the other groups of animals listed. They are better adapted to their aquatic environment than most other life forms. They have found their way into many niches and developed many unusual behaviours that better allow them to cope with their environment.

Adaptation to life in rivers

The upper parts of river have fast flowing turbulent waters with little mineral content. The fish that live in these waters have adapted by becoming streamlined and fast swimmers and are able to mainatin a stationary position relative to the river bed while water flows past them. Because of the noise from the turbulent waters these fish have developed better eye-sight and lesser hearing ability. These adaptations help predator fish to better hunt their prey and also helps fish to avoid predation by larger fish and other predators.

Mid river, further downstream, is where the flow of the river is less and the river widens. Fish found in this part of the river are usually deeper bodied and less stream lined. Water in this part of the river is usually clear which aids fish with good eyesight.

In the river low lands the river becomes even slower and even wider. The water is usually cloudy with dissolved decaying vegetable matter and tannins from submerged logs, pieces of wood and roots.

Because of the water cloudiness in this part of the river fish cannot rely so much on their eyesight. They instead have developed better sense of smell, taste and hearing. Many shoaling fish in this part of the river have developed bright or even reflective scales to enable them to see each other in the murkiness.

Adaptation to life in ponds

There are other tropical fish that have adapted to live in lakes and ponds of Asia. During the hot and dry seasons the ponds and small ditches evaporate and reduce to small and stagnant bodies of water. Gouramis are a class of fish that have adapted to these low oxygen conditions by developing the ability to breathe air. They achieve this by gulping air into a specially adapted labyrinthian organ that absorbs the swallowed air. This allows them to survive in low oxygen conditions that would drown normal tropical fish.
These ponds and lakes are usually muddy or cloudy so having good eyesight is not such an advantage. Fish in these cloudy conditions have developed barbels near their mouth to help them find food. The gouramis have developed a pair of thin hair like fins that they use to feel and taste their surroundings and help them find their way through the thick vegetation. Fish in these cloudy conditions have also developed a better sense of smell.

Where and how to buy livebearers

Here are the main sources of livebearers

Your local aquarium pet store is a good source of fish
Your local aquarium pet store is a good source of fish

You can of course go to one of the large pet chain stores where you will be able to buy some off the shelf guppies, platies or mollies and sometimes swordtails. However don’t expect any fancy variety or high pedigree fish. If you are a beginner just starting out then this is not a bad place to start out. You will however have to be more careful with the health of the fish you buy here because these are not cared for by experts in fish keeping but by shop staff who may not have experience in looking after fish at all.

There are smaller specialised aquarium shops that will carry a greater variety of livebearer and occasionally will stock the excess brood of a professional breeder. You might be able to pick up some near pedigree stock.

Aquarium clubs are a much better place to buy more specialised forms and rare species of livebearer. You will also be able to buy wild strains of newly imported fish that are not available anywhere else. The American livebearer association or the British livebearer association are the obvious clubs to join. Other local clubs are less likely to have livebearers that you might particularly want.

internet classified adverts is a good source for fish
internet classified adverts is a good source for fish

You can also browse aquarist magazines in the classified section to see if the livebearer you are after has come up for sale.

Before buying your fish, it is best to inspect it first. Be prepared by taking with you several plastic bags and a polystyrene carrier box to take your fish home comfortably without much heat loss. Before you set off to buy you must have your home aquarium all set up.

Now, with the spread of the internet you can also buy fish from an online source. There are several good options available to you. Ebay, craigslist, gumtree, and others have a good fish for sale section. Aquarist classifieds has several specialised fish for sale sections that are also sorted by area.

There are also online firms that do mail order tropical fish. They deliver tropical fish to your door overnight no matter where you live in the country. But sometimes when the weather is particularly cold they might not deliver. Another drawback to this is that you cannot inspect the fish before hand. Home delivery of fish relies on mutual trust from the buyer and seller. The advantages are that you can pick exactly the fish you want with you having a wide choice. Also you do not have to make wasted journeys looking for your fish. The cost of delivery can be reduced by buying several fish at the same time.

In the winter some firms will deliver fish but will include special heat packs that maintain the temperature of the water for 24 hours until they can safely reach you. These are expensive and you the purchaser will have to pay extra for this delivery method.

Always buy healthy livebearers

How do you recognise a healthy livebearer? Once you have picked out the fish you are interested in, take a good long look at it in the aquarium. Also, look at other tankmates that share the same tank as well. Examine the body for any white or grey fuzzy patches. Examine the fins for any splits or frayed edges. Check for any abnormal swelling of the eyes or swelling of the abdomen. Check for any scales that stick out pine cone like. Look at the gills they should not be red in colour. check the belly of the fish. If it is concave or the head of the fish looks too big for the body. This is a sign of a poor upbringing. If any of the previous symptoms are present in the fish you are considering then do not buy the fish.

Your ideal fish should have scales and skin with bright colours and have no white grey,brown spots on the skin. The skin should not have a cloudy mucous or fluffy patch anywhere. The fins should be held proud and erect, held away from the body. Clamped fins are a bad sign. Frayed fins are a sign of ill health.

Examine the mouth of the fish. The fish should not have white/grey patches around the lips. The mouth should be sharp and clear.

Next observe the fish swimming. The fish should be active not skulking in a corner. It should show signs of wanting to feed when you come near the aquarium. The fish should not be stuck to the floor of the aquarium nor should it be stuck floating at the surface. This is a sign of swim bladder problems. If you see any of the fish in the aquarium with their mouths near the surface gasping for air and gills opening and closing then this is a sign of poor water conditions(but don’t confuse this with fish trying to feed).

Can I buy just a single livebearer?

It is best to buy a group of fish together because livebearers are social animals and develop inter-fish relationships such as dominance and recognise familiar individuals. You can buy a single fish to add to an existing aquarium but be careful of bullying of the newcomer. Swordtail males will fight each other so it is best to buy only 1 male for any individual aquarium.

How many male and female livebearers should I buy?

If you are buying young fish then to guarantee a reasonable group of males and females you should buy 6 or more because there is no way of telling the sexes apart at a young age.

If you buy adult fish then you can distinguish the males from the females.

  1. Males are more colourful than females. Females are dull in colour but may have some colours in the fins.
  2. Males are usually smaller than females of the same age.
  3. Males have a stick like ventral fin, where the females have a normal triangular shaped fin. The males use this fin to fertilise the females. This fin is located near the fish’s vent.
  4. The males have larger dorsal fins than the females.
  5. Males are slim built while females are plump in shape.

Once you learn to tell apart males from females then you are ready to buy a breeding group. Try to buy 2 females for every male.

Best time of the year to buy livebearers

There is a greater abundance of fish for sale during the spring, autumn and christmas time. So these are the best times to buy your fish. When you buy your fish make sure you don’t have a holiday or business trip planned in the weeks after purchase. It is best to be there for the first few weeks while your fish settle in to oversee if there are any problems.

How to bring your newly bought livebearers home

Set up your home aquarium before you start looking for fish. It should ideally be cycled with a mature filter. After you have purchased your prized specimens always head straight home. When you arrive home, immediately place the unopened bags in the aquarium water.

Leave the fish in the bag for at least 15 minutes to give a chance for the water temperature to equalise with that in the tank. After that you can slowly top up the bag with some water from the tank. Wait 5 minutes then top up again with some more water. Keep repeating until the bag is full. Then release the fish into the tank.

If you have bought small fish or baby fish less than an inch long then you can bag them together in large bags, 4 to a bag. You should put adult fish or fish an inch or bigger in size, singly into separate bags. The bags should be filled with 3/4 air and 1/4 water by the person selling you the fish. They should use the water from the aquarium the fish came from.

Quarantining your newly bought livebearers

When you become serious at the hobby and have prized specimens at home that would be a great loss if they died then you must use a quarantine tank to keep your new arrivals away from your established fish. This gives you a chance to see if your new fish have any hidden illnesses or not. Keep your new fish in quarantine for at least 2 weeks, but better still for 4 weeks to be absolutely safe. If the new fish appears well after this time then they can be transferred to the main aquarium.

Have the right livebearer aquarium set up

Most livebearers can live quite well in a community tank. Your community tank can consist of a variety of livebearer species, a single livebearer species or even include some other community fish alongside. The choice is yours.

Use a single species tank if you are line breeding pedigree livebearers. Note that some closely related livebearer species can interbreed and you will end up with unwanted mongrel fish.

When having a community tank you should try to make sure all the fish are of a similar size and similar activity level. This will help to reduce bullying of small fish by bigger fish and active fish stressing out more placid fish. Also the more active fish will always get to the fish effectively starving the less active fish.

You should always include more females than males for all species. A ratio of 2 females to every male is a good starting point. This is because most males will be continually trying to mate with the females. Too much male attention stresses the females.

Livebearers generally prefer hard alkaline water of ph higher than 7.5. Some species even benefit with some sea salt added to the water. The main species of livebearers prefer temperatures between 74-80f. However the sunset platy a close relative of the common platy prefers lower temperatures between 70f and 75f. Goodeids also prefer lower temperatures similar to sunset platies.

Compatible fish for a livebearer community tank

Most small tetras are compatible with guppies, mollies and platies or other similar livebearer species.

Small corydoras catfish are ideal for most livebearer tanks because the corys stay along the bottom avoiding the livebearers who mostly live along the top of the aquarium.

Most dwarf cichlids make ideal companions because they also occupy the bottom of the aquarium and are not overly aggressive. The presence of livebearers in a dwarf cichlid tank actually gives the dwarf cichlids more confidence to come out more rather than hiding in plants and caves.

Barbs, rasboras and danios are a little more active and occupy the same space as livebearers but can still make good companions for medium to large livebearers such as swordtails and sailfin mollies.

Even for a livebearer single species tank, the addition of a few corydoras catfish can liven your aquarium by having some activity in the lower half of the tank which is usually deserted in a livebearer aquarium set up.

How to set up your tank fish from top to bottom

To increase the chances of your fish being compatible you need to consider the fishes’ territory. Fish swim in different zones of the aquarium. Some swim near the surface. Some swim midwater. And yet others stay near the floor of the aquarium. Generally fish in one zone will be less territorial with fish from another zone.

Here I will list suggested fish groups by tank size with an eye on maximum compatibility.

About fish shows

Gozo fish show
Gozo fish show

You’ve learned to keep your fish from dying. You have managed to breed your fish. Now what? Entering your fish into a local fish show is a great next step in taking your fishkeeping hobby to the next level.
With experience you can win trophies, ribbons or prizes such as aquarium equipment or money.
You can show off your prized champion fishes and your skill at raising and breeding your fish.
Fish shows are a good place to keep abreast of new products. Many new products and different interesting species are usually on display.
Usually there are door prizes giving the entrants many chances to win fishkeeping equipment such as heaters, filters or lighting.
You will certainly meet fellow aquarists who will be expert in various fields of fishkeeping. You can learn a lot by asking questions. These experts always take great pride in answering questions, so that they show show off their great expertise on their favourite subject.
You can also ask company representatives of manufacturers about any equipment that they have on display and advice on equipment in general.
You may have to attend shows a few times to see what your competition is like before you will be ready to start entering your fish into the show.
It is only when you start showing off your fish that your fishkeeping skills will really improve and you will become a real expert.
Only through research, and putting into practice what you pick up will you be able to consistently high quality show grade fish.

Different types of fish shows

Most aquatic competitions are organised by aquarium societies. Some are very large such as the International Betta Congress (IBC) or local to large towns or cities.

Small fish shows

Small fish shows are sponsored by local clubs. To enter a fish into one of these shows you do have to be a member of the local club.

Regional fish shows

These are shows where different clubs compete against each other. A regional show forces you to cooperate with other members of your club in a team effort.

Open fish shows

Same as regional shows except that these are open to the general public and not just members of any particular fish club or aquarium society.

Fish exhibitions or Aquatic Conventions

These are the largest shows that you can enter. These types of show are hosted by tropical fish magazines and international societies.
Many aquarium equipment manufacturers will be present. They usually showcase their latest product line in aquarium filters, lighting, aquariums and aquarium equipment. They will try to sell you something if you look like a prospect.

How fish shows work

Understanding classes in fish shows

Here a judge is grading discus at a show
Here a judge is grading discus at a show

Fish shows put fish into classes so that similar fishes will be judge against each other. Fish shows have many rules for a fish class. You will have to make an effort to understand these rules and comply with these rules to have a decent chance of winning.
Fish have to be compared like for like to make it fairer and easier for the judge to make a decision. That is why you have to enter your fish into a specific class. Make sure you put your fish into the correct class. Classes are grouped by similar species. Groups such as livebearers, central american cichlids, dwarf cichlids and the like are examples of classes and should be easy for you to decide which class is best for your fish to be entered into.
Classes can be further divided into sub-classes. For example a livebearer class can be divided into guppy, platy, molly and swordtail classes. Then guppy class can also be further sub divided into tail type classes such as spade tail, round tail, lyretail, etc. Make sure your fish is suitable for the class you intend to enter it into.

Increasing your chances of winning a fish show

Try to prevent or discourage people from looking at your fish before the judges arrive. You don’t want your fish to be unnecessarily stressed before the judges have arrived. Stressed fish may lose their colour.
You can actually train your fish not be be spooked out by strangers coming to inspect them. What you need to do is recreate competition-like conditions for your fish at home.
Place your fish’s holding tank somewhere lots of people will pass to and fro in front of, with the occasional person peering into the tank. Or arrange for several members of your family to pace back and forth near the tank several times a day. And also tell them to peer into the tank, while you observe your fish’s behaviour. When the fish becomes accustomed to this attention then you can train less often. Also you can try shining a torch at the fish occasionally so that when the fish is at the show the fish will not be startled by a judge with poor eyesight flashing a torch at your fish to better see it.

Never present ill fish at shows. Only take fish that are in tip-top to the show. The stress of the show and the travelling to and from the show does put a fish under stress. Such stress can kill or make ill a weak fish. You will not be popular at the show if you bring a sick or weak fish.
A small holding tank can be used to keep your fish safe and well before the show so that your prize fish can avoid getting into a fight or injured with other fish. You can also keep a close eye on your fish’s health. Feed live food and vegetable tidbits in preparation for the show. Make sure you clean the tank with water changes and syphon off any waste matter daily.
Don’t include decorations in the holding tank that may injure your fish. You can however include floating plants and some java moss or java ferns. Have a bare bottom or a thin layer of sand at the bottom of the holding tank.
Your fish needs to be relaxed and stress free in the holding tank. And maintenance and observation will be easier.

Exhibiting your fish in a professional manner

Get hold of a copy of the rules for the class you expect to show your fish in. Study the rules carefully before you fill out an entry form so that you can familiarise yourself with the rules of the contest you want to enter your fish into.
Take your fish to the show early so that your fish has time to settle down. Stressed fish may have washed out colours. Adding a little salt to the holding tank can help your fish regain its colour.
Always take water from home with you to the show. Do not use water from the show, which may be markedly different than the water you have at home. Many owners who ignore this end up with sick fish after the show. Also for a day or two before the show stop feeding. This will not harm your fish, but will reduce any toxins in the water and your fish will become more active.
Always use a show tank that is the appropriate size for the size of fish that you will be showing. A small fish in a large tank will look lost, while a large fish in a small tank will look cramped.
Make sure you read the rules in regards to the set up of the show tank. Some shows don’t allow gravel. Make sure you clean the glass throughly on the outside of the tank and inside.
When your show tank is all set up then stand back and look at the whole set up with the fish inside. Look at it with the eye of a judge. Make adjustments where necessary.

Show guidelines for showing fish

wonderful champion crown pearlscale goldfish
wonderful champion crown pearlscale goldfish

Judging guidelines are usually very strict. Contestants are usually not allowed near their tanks when the fish are being judged. So, be patient.
Each class has a single judge who will judge and score your fish on its own merit and not in comparison to neighbouring fish.
After all the fish in all the classes have been judged, a best of show award is given to the best fish in the show overall.
Aquarium societies have set up benchmarks or standards that each fish can be directly compared to. Obviously the fish that is closest to the benchmark is usually judge to be the winner.
Most fish are judged on a point system. Points are allocated in sections. Some points for size, some for shape, some for colour, finnage and deportment. Some sections are appointed more points than others, so be aware of this. The fish with the most points altogether is the winner.

Size and body weight of show fish

Size is a consistently high scoring factor. Bigger fish score more than smaller fish.
The fish’s body must be fully intact. No bumps or growths or deformities. They are not tolerated well by the judges. The fish’s body must be of the correct shape and correct proportion. The fish should not look bloated or anorexic.

Colour and fins of show fish

A fish’s body colour is determined by various layers of pigmentation that is found in the scales and the flesh underlying the scales of the fish. In the wild, colour is used for camouflage, display, mating and for shoaling purposes.
In shows, the fish must meet the the show standards for colour which might be markedly different than wild colours. Many show fish have colours that have been mutated over many generations away from the original wild colouration. Colour can be a very important factor in scoring for a show and a lot of points out of the total go to good coloration.
Fish do have some chameleon like abilities when it comes to colour. They can adjust their colours to better blend in with their surroundings. In bright tanks they can become washed out while in dark tanks they can darken.
Your fish’s coloration should be even all over the body and fins. The colour should not look washed out or be in patches unless it is a patterned fish.When 2 or more colours appear on a fish the borders where 2 colours meet each other should be well defined without colour bleeding.
Do not be tempted to use artificial colouring methods to improve the colour of your fish. These techniques leave the fish looking artificial and most judges will instantly recognised an artificially coloured fish and disqualify it.
Fins should all be present and well formed. Any missing or deformed fins are severely frowned on by judges. It is better to not enter such fish because you want to build up a good relationship with the judges for future shows. All fins must be in good condition with no tears, splits or frayed edges. The fins should all be held wide open and properly coloured. The fins should all be symmetrical in shape and size.

Overall condition of show fish

There should be no missing or damaged scales. Eyes should be bright and clear and symmetrical. The eyes must not be bulging or look sunken. The fish must be in perfect health and have a healthy and alert appearance.
Transporting fish to and from a show
Transport the fish’s display tank in an insulated wooden box. Darken the tank by covering with a cloth. Cushion the tanks so that vibrations and jolts are not transmitted to the tank and the fish. Make sure you arrive early to set up your show tank and give your fish time to settle after their stressful journey. Relaxed fish always display better and always score better than skitty fish with stressed colours.

More about background plants here

A midground plant is a plant that acts as a filler in the mid area of the aquarium. Usually planted as individual plants. Midground plants should have distinctive large leaves and colour. They should be short plants to not block out the background. A good midground plant will stand out against the background without dominating the scene. Midground plants create the ‘body’ of the aquascape, whereas background plants create the skeleton of the aquascape.

I will list below recommended midground plants for your aquarium that are easy to care for.

Anubias barteri known as broadleaf anubias

Anubias barteri makes an excellent midground plant

This is a slow growing plant that has tough, firm dark leaves and is recommended for an aquarium with fish that destroy plants. It should be planted singly in the midground. They prefer a heated substrate. Needs moderate to bright lighting. Temperature range of 72F-82F. ph of 5.5 to 8 and moderately soft water.

Giant Bacopa

This is a fast growing plant that likes bright light and can be kept in hard watere. It is a stemmed plant with medium spade shaped leaves all along its stems. Can be propogated by taking cuttings. Leaves can turn red under very bright light. It can tolerate lower light levels. Temperature range 68F-82F. Water ph 6.5-7.7.

Japanese Cress

An unusual plant with a disorganised growth pattern. It is not strictly tropical so should only be used in the unheated aquarium. It is hardy except that it can be affected by medications and chemicals. It does prefer bright light. Temperature range is 61F-72F. Water ph 6.5-7.8.

Stargrass

This plant can grow tall and should be trimmed down. The leaves are long and slender and grow out in groups of 5,6,7 leaves giving it a star like shape. They do better with a little fertiliser occasionally and good lighting. Temperature range is 72F-80F. Water ph 5-7 and low hardness is preferred.

Water pennywort

The leaves of this plant are large and round with lace like edging. The leaves grow all along winding and branching stems. This plant will try to reach the water surface, where it will grow leaves that block out the light to the aquarium below. So, trim back before the plant reaches the surface. It prefers bright light. Temperature range is 68F-82F. Water ph range is 6-8.

How to recognise good background aquarium plants

What is meant by ‘background plant’? This refers to plants that will be placed along the back and sides of your aquarium. These type of plants usually grow tall and cover most of the rear of the aquarium. And finally they usually provide a good background contrast to foreground plants. This is achieved by having bushy growth or fine leaves. Listed below are the best background plants in terms of beauty and ease of care.

Magenta Water Hedge (Alternanthera Reineckii)

red water hedge plant nice alternative to green

This is a plant that will contrast well against other green plants because of its red/purple coloured leaves.

Because it is a little short it has to be planted in groups to form an effective background or as a space filler between taller plants. There is a taller variety that does make an ideal background plant.

Allow space between each stem so that each plant will obtain enough nutrients from the substrate and also they don’t block each other’s access to light. It does need good lighting or it will not thrive. Push fertiliser tablets near its roots because they do like a lot of nutrients. The water hedge prefers neutral to slightly acidic and soft water with a temperature range of 72F-80F. Hardiness is average.

Green Cabomba

fast growing green cabomba with bushy fronds

This is a plant that needs strong lighting and fertilisers tablets near its roots or it tends to disintegrate. It is better to keep the aquarium water well filtered because the fine frond like leaves collect debris. Plant cabomba in groups. Easy to propogate by taking cuttings from the top. Prune when it grows too long. Temperature range is 60F-80F. It prefers water that is around neutral in ph with a moderate hardness. It is medium in difficulty to care for.

Onion Plant

This plant sometimes known as the aquatic onion plant resembles an onion plant but is unrelated. It grows long slender but thick leaves that don’t branch. It has a bulb above its root system. The leaves tend to spiral slightly as it grows. It is a tough low maintenance plant. It is good with cichlids and goldfish. It needs moderate lighting. Temperature range of 64F-80F and can handle a wide range of water conditions around neutral ph and moderate hardness.

Cryptocoryne Balansae

cryptocoryne balansae variety crinkly leaves

This plant has long slender crinkly leaves with pointed tips. It can grow well in hard water and can be grown under different brightness. However it will grow faster in bright light. It propogates by sending out runners with plantlets that grow on the runners. It is a hardy plant and easy to care for. Plant in groups for a nice effect. One of the best background plants. Temperature range 73F-82F. It likes a wide range of ph between 6-8ph and a moderate hardness level.

Broadleaf Amazon sword plant

This is a good beginners plant and makes a good background plant but does need to be kept pruned because it grows large. It needs a reasonably bright light. It can cope with a temperature range between 68F and 82F. Does benefit from the occasional fertiliser tablet. It does not care much about its water chemistry as long as extreme conditions are avoided.

Ruffled Amazon sword plant

This is another easy to keep amazon sword variety. It is more bushy than the broad leafed amazon and its broad leaves have an attractive crinkle to them. It needs the occasional fertiliser tablet and some good lighting to thrive. Temperature range of 72F-82F and likes a wide range of ph and hardness with slightly acid being preferred.

Spadeleaf plant

The spade leaf is an easy to care for background plant
The spade leaf is an easy to care for background plant

This is a very broad leafed plant. It is easy to look after and grows quickly when supplied with bright light and tablet fertilisers. It can become quite bushy because of its fast growth. It likes a temperature range of 50F-82F. It likes a wide range of ph and water hardness.

Water wisteria

Water wisteria is an easy to keep plant with finely branched leaves. Use a table fertiliser near its roots and a bright light to ensure good growth. Water wisteria likes a temperature range of 73F-82F. Likes average water conditions around 7 ph but is not too fussy.

Dwarf Hygrophila

This is a popular aquarium plant and for good reason. It is low maintenance and very hardy. It will grow under nearly all aquarium conditions. Plant in groups of five in the background to create a bushy background. It does grow rather quickly. It does prefer bright light but can get by in moderate lighting. The preferred temperature range is 64F-86F. Ph range 5.0ph – 8.0ph.

Green myriophyllum

The green myrio is a great beginners background plant
The green myrio is a great beginners background plant

A great looking background plant that creates a fine leaved layer of green bushes all along the back of the aquarium. Keep the aquarium well filtered because debris in the water will collect in the plants fine leaves. Temperature range between 59F-77F.

Dwarf Rotala

Dwarf rotala is a stem plant with leaves that grow all along single stems. In bright light the leaves take on a reddish colour over the green. This plant grows quickly when kept in brightly lit aquariums. It is an easy to care for plant. Temperature range is 68F-84F. Ph 5.5-7.5.

Straight vallisneria

The vallisneria is a tough, easy to care for plant. It reproduces by sending out runners on which plantlets sprout out. Each plantlet can be cut off when the plantlet has grown roots. It will grow quickly in the right conditions. Because of this it needs to be thinned out by separating out the leaves of the plant. vallisneria grows best in bright light but it will tolerate low lighting conditions. It is best planted in thickets surrounding the back and sides of the aquarium. Temperature range of 59F-86F. ph range is ph6-ph8.5.

The corkscrew vallisneria is prettier than the straight version but not as tough
The corkscrew vallisneria is prettier than the straight version but not as tough

Corkscrew vallisneria

The corkscrew vallisneria is similar in appearance to the straight version but with spiral leaves. It is not as hardy as the straight leaved version and needs moderate to hard water to thrive. And will not do well unless bright lighting is provided. Temperature range of 75F-82F. Ph range is ph6-ph8.

About Aquascaping

balanced aquascaped rocks, plants, gravel and fish
balanced aquascaped rocks, plants, gravel and fish

Aquascaping is the art of setting-up, decorating and arranging aquatic plants along with stones, rocks, driftwood or cavework in an aesthetically pleasing manner. Also termed as underwater gardening, aquascaping was first introduced to the world way back in 1990’s by Takashi Amano from Japan, who made the natural underwater gardens look like dreamscapes. Although it is possible to create an aquascape with plants only, it can also be set up with fish as well as plants; or with rockwork, hardscape and no plants by following some specific methods.

If you find it difficult to create an aquascape then scan through the many examples of good aquascape scenes on the internet and pick a scene that you really like and that you can replicate.

Basic Principles for Aquascaping

To reach the perfection in the design of your aquascape you must follow a few important principles that are listed below:

Simplicity is the key – While aquascaping is all about imagination, it is recommended that you follow a particular style and maintain simplicity which would make the aquascape look more appealing to the human eye.
 
Choosing the aquascaping style – There are several major styles that you can choose from, which you can create a visually-enticing aquascape. These include the Japanese-inspired nature style, the garden-like Dutch style, the jungle style and many others. While the nature aquarium style is the re-creation of terrestrial landscapes – mountains, hills, valleys, etc., the Dutch style is characterized by terraces or raised layers containing distinct types of plants with different leaf types.

Maintaining Proportion- To maintain harmony in the aquarium, it is crucial to strike the perfect balance between plants, decorative items and fish as well as between filled and empty spaces in the aquarium. Also, arrange plants, rocks and wood in a manner that there is a balancing contrast of light and dark spaces.

Use your imagination- There are no defined rules for aquascaping. Use your imagination to make a beautiful aquascape that has clean water and an appropriate amount of light, CO2, and other essential elements.

To ensure proper care, maintenance and success of an aquascape, aquascapers must keep in mind several factors to strike balance in the closed system of the water tank. These factors include:

  • aquascape with clever use of various plants and driftwood

    Filtration System

  • Liquid fertilizers
  • Medium to high level of lighting
  • Maintaining the correct amount of carbon dioxide to support photosynthesis
  • Frequent water changes
  • Substrate and fertilization
  • Algae control

Plants and Plant Types

Besides the layout, style and design of an aquascape, aquascaping require specific ways to ensure proper care and maintenance of plants underwater. One of the most crucial things that aquascapers must keep in mind is choosing healthy and vibrant plants. Also, they must be trimmed to get the desired shape and positioned properly using a thread. Before beginning, you must know the plants and plant types that we shall discuss now!

Carpet Plants: Just as the name suggests, carpet plants are used by aquascapers to create a mat of plants or a lush of green lawn, making the underwater garden more beautiful and attractive. You can choose foreground pl ants such as Hairgrass, Dwarf Baby Tears, Java Moss, Water Wisteria or Willow Moss as they stay low to the ground and spread horizontally across the floor of the water tank.

Fast Growing Plants: When you begin with aquascaping, you can choose fast growing plants like hornwort, Vallisneria, Cabomba and Hygrophilia that would grow quickly, with no effort and would not even put a hole in your pocket. Other stem plants including sword plants, Java fern are also suitable but a little expensive.
Floating plants: While a number of floating plants can block light, many aquascapers prefer using them for visually-enticing aquascape. These plants include Hornwoot, Java Moss and Najas.

Artificial Plants: While using artificial plants is not considered aquascaping, it is one of the easiest ways for beginners. So, if you find it difficult to care for and maintain natural plants, you can go for artificial plants that do not require light or water parameters.

Location for Short, Large and Bushy Plants

To create a beautiful landscape underwater, it is essential for aquascapers to place the plants in an aesthetic manner. The major aspect to keep in mind is the focal point. It can be anything like a rock, a piece of driftwood or a bunch of plants or even one dominant plant. It is recommended to begin with carpet plants at the foreground and place the bushy and large plants at the background.

You can begin with the focal of the water tank and continue with the low-growing and mid-growing plants. At the end, place the higher plants. You can choose an appropriate composition such as the concave set up, the convex set up, the rectangular set-up, the triangular set up, or the Iwagumi set-up.

Different Coloured plants

To create in-depth perspective and make the aquarium look more natural, aquascapers use plants of different colours and sizes. Plants can be grown in groups and with rich colour contrast. Commonly used plants for colour contrast and highlights include lutea, lucens, wendtii, walkeri, and becketii of the Cryptocoryne species, Ammania, Alternanthera reineckii and Rotala.
Notably, 3 plant species per foot would be preferred to ensure good colour contrast.

Open Spaces for Fish

Before you kick-start aquascaping, you must understand that plants as well as fish are EQUALLY important in your water tank. When you provide the best conditions for your plants to stay healthy, you are providing a healthy environment for the fish as well. At the same time, it is a must to wisely use spaces between plants by creating imaginary streets as well as pathways. Also, make sure that you have as must open space as must filled space to provide space for your fish to lively comfortably and happily.

Hardscape: Use of Bogwood/Driftwood

Hardscape is one of the most commonly used techniques used by aquascapers across the globe. It involves using driftwood, rocks and resin sculptures. Driftwood adds a decorative touch to the aquarium, while making it look natural. The wood can be the main focal point, around which the plants can be placed. Many aquascapers prefer using the Malaysian driftwood or manzanita branches, depending on their preference.

Use of Rocks and Stones

In addition to wood, aquascapers use rocks and stones at the heart of their aquarium to create a natural-looking aquascape underwater. You can place boulders, large cobbles and smaller pebbles aesthetically in the water tank to further enhance its beauty. The classic way to use rocks is to place 2-4 flat rocks on the bottom of the aquarium and then arrange other rocks in the order of their size. Alongside, you can also add airstones and submersible lights to create visual effects and make the water tank more attractive.

Get Started!

Aquascaping is not all about creating a plan and sticking rigidly to it. Sometimes it is better to do a quick sketch up and then proceed to plant according to your rough draft. Then when it’s all laid out, you can see that it might not be right so you will need to rearrange things until you get it right. And don’t forget plants do grow and some grow more than others. So your aquascape will actually develop over time.

Aquascaping is all about imagination and creating enchanting visuals that appeal to the human eye. So, make sure that you use your imagination to create an amazingly-looking aquascape. Happy aquascaping!

The 20 most popular fish and how to feed them

The 20 most popular fish and their favorite foods

Suggested beginner fish groups

Fish foods

Fish are just like any other pet when it comes feeding—they need to be fed regularly, and different specimens will assuredly have different tastes and preferences. Your choice of fish food will readily affect the health and wellbeing of your fish, so you want to make sure that you make the correct choice concerning your particular species of fish.

It should be noted that in some cases, certain combinations of fish foods will help encourage breeding. That is normal day to day feeding needs to be enhanced when you need to prepare your fish for breeding. In most cases, live foods such as brine shrimp are best, since their presence gives some fish species a cue that the environment is ripe for breeding. In the list that follows below, you will see breeding options added on where appropriate.

Food options and feeding for the most popular fish.

There are two broad categories when it comes to fish food: processed foods and live foods. Of these two choices, live foods such as brine shrimp and bloodworms are generally superior, but often require cultivation. Processed foods, on the other hand, are inexpensive and easily obtained at any aquarium supply store. Among the processed choices, there are further options, including:

  • Fresh foods
  • Frozen and freeze-dried foods
  • Canned flakes or pellets
  • Sinking Food Tablets

Flake food is generally the most popular of these options, but the list below will show that certain species have much to offer the enterprising aquarist who invests in a supply of specialty foods.

The favorite foods of the 20 most popular freshwater aquarium fish

  • Angelfish—This tall community-friendly fish is not a fussy eater. Angelfish will gladly live off of a variety of commercially available flake foods and freeze-dried options. For the best results, supplement its diet with some fresh bloodworms, brine shrimp, or even leftover vegetables like peas.

  • Bettas—These extremely popular fish are easy to take care of. They will accept canned flake and freeze-dried foods, but they do their best with small fresh worms. Specialized Betta foods are widely available at pet stores, and breeding can be encouraged using live foods.
  • Barbs—The barb family of fish consists of numerous species that share, among other attributes, a major appetite for just about anything they can fit in their mouths. Barbs love flake, they love frozen foods, they love worms, and they love your aquarium plants. Make sure your barbs are getting a dose of vegetable fiber so they’ll leave your plants alone.
  • Guppies—Live-bearing fish that are commonly seen in a wide variety of community tanks, guppies have a great appetite for small live foods. They will also eat frozen worms and flakes, and have a particular fondness for variety. Try feeding them the occasional slice of zucchini or other vegetables.
  • dalmation molly male
    pedigree dalmation molly

    Black Molly—These beautiful black fish are useful algae-eaters for your tank. However, they will need to supplement that food source with flake food or blanched vegetables. The black molly feeds at the surface of the tank, so make sure your food floats, or the fish may not find it.

  • Serpae Tetras—These small and very popular fish are known to nip away at their neighbors fins. They are not picky eaters, but extra care should be taken to make sure that their tank mates also get to eat. These fast-moving fish can quickly consume more than their fair share of food, leaving slower fish unfed.
  • Rummynose Tetras—Your red Rummynose tetras will survive on a diet that consists of commercially prepared flake foods without issue. They are perfectly fine with dry and frozen foods, but prefer live brine shrimp, mosquito larvae, and brown worms.
  • Rosy Tetras—The abundantly seen Rosy Tetra prefers a diet that consists of flakes and worms. These fish will eat very small fish if given the chance, so care should be taken if you choose to combine them with juveniles or fry.

Pristella_tetra

  • Black Tetras—Very popular fish for beginners, Tetras are not picky about what they eat, and will even breed on a diet of dry flake food. Your black tetras will be perfectly happy with anything even remotely resembling fish food. Give them a good quality flake-and-vegetable diet to ensure their best health.
  • Blue Gourami—This species of fish, like most of its Gourami cousins, will exhibit its best coloring and behavior when given a diet of small live foods with leftover vegetable matter such as zucchini or peas. They will eat flake and freeze-dried foods, as well, but higher quality options are recommended.
  • Kribensis—These undemanding fish are perfect for beginners. They are tolerant of most water conditions and food sources. They will eat nearly anything, but offer the best results when fed a combination of flake food and frozen bloodworms or brine shrimp. Being middle to bottom feeders, you can try sinking pellets.
  • Discus—These cichlids are peaceful, tall fish that are very popular for larger community tanks. They will accept flake food, but should be given more in order to encourage the best health: frozen or live worms, shrimp meat, and Spirulina to enhance their coloration. Discus fish will happily eat chopped up beef heart.
  • oscar2
    Oscars are popular but can grow very large and eat a lot of meaty foods

    Oscars—The oscar is an intelligent fish that will learn to recognize its owner. It is also a characteristically aggressive fish, and it will eat its tank mates if given the opportunity. Naturally, this fish does best with a meat-based diet. Live worms are ideal, but frozen ones are acceptable as well. Do not feed your oscar guppies or other fish.

  • Catfish—Corydoras and related species of catfish are bottom-dwellers that will gladly eat any food that falls to the bottom of your tank. In order to make sure that enough food reaches your catfish, purchase some sinking tablets. Corydoras will only breed if worms, with blackworms being a particular favorite.
  • Zebra danios—This very popular fish prefers a diet consisting of a wide variety of small live food choices: bloodworms, brine shrimp, Tubifex worms, and insect larvae are favorites. They will also accept frozen and flake foods, but you should take care to supplement the diet of this fish with romaine lettuce or other green leafy vegetables.
  • Frontosa cichlids—Possibly the most popular fish from Lake Tanganyika, the frontosa cichlid likes meat. Some specimens will ignore flake food, requiring you to provide a steady, varied diet of krill, worms, or daphnia. This fish is one of the few that can be trained to eat directly out your hand.
  • Jack Dempseys—These aggressive fish are popular pets since, like Oscars, they will identify and develop a relationship with their owner. They are not picky eaters, and will gladly thrive off of a diet of flake foods or just about anything else.
  • white cloud mountain minnow pair
    white cloud mountain minnow male and female

    White Cloud—This popular beginner’s species is very happy to live on a diet of canned flake foods. Supplementing that diet with live foods such as brine shrimp or even frozen bloodworms can help: extra nutritional options like these will intensify its colors.

  • Platies—The live-bearing platy comes in an enormous variety of colors, sizes, and finnage types. These community-friendly fish will are content with commercially-prepared flake food, but will thrive if given an extra boost of vegetable matter in their diet. With a vegetable-heavy diet and some aquarium plants, they will readily breed.
  • Goldfish—Last, but not least, the ever-popular goldfish is happiest when presented with live worms, but will feel perfectly fine when provided with flake and sinking pellet foods. The key with goldfish is recognizing that they look for food either at the surface of the tank or at the bottom. Choose a food that sinks or floats to make feeding easy.

Fungus – the ever present danger to fish and eggs

Fungus – the ever present danger – to fish and eggs

This golden julie from lake tanganyika has fungus
This golden julie from lake tanganyika has fungus

There are many species of aquatic fungus but by far the most common two are saprolegnia and achlya.

Symptoms of fungal attack

Fungus occurs as white, grey and sometimes brown fluffy growths on the skin or fins of fish or on developing eggs from a spawning.

Saltwater fish actually suffer less, than freshwater fish, from fungus because of the salt in a marine environment. However, brackish water fish, even mollies, when kept in insufficiently salty water are the most prone to fungal attacks.

Fungus often starts as a small tuft, and usually spreads when not treated and can kill a fish if the fungus penetrates the internals of the fish. Fish eggs if not treated or infected eggs are not removed can cause all nearby eggs to be infected and killed.

What causes fungus to develop

Fungus and fungal spores thrive in damp environments with decaying organic matter and an aquarium is full of water so is ripe for fungal outbreaks. Fungus sprouts where there is decaying organic matter, dead fish, or unfertilised or dead fish eggs. When fungus grows it releases millions of spores into the water which will quickly infect any fish that has a break in its protective mucous which may occur after rough handling or an attack from another fish or bumping into aquarium rocks.

Parasitic diseases such as ich, body ulcers and infections will damage the protective mucous and allow entry of fungal spores, compounding the fish’s problems.
When fish are kept in poor quality water conditions with water that is full of bacteria, nitrites, ammonia and excessive fish waste then they are much more likely to get infected by fungus.

Fungus treatment for fish eggs

Several eggs from this spawn are starting to get infected
Several eggs from this spawn are starting to get infected

With fish eggs any unfertilised eggs or dead eggs will quickly get infected with fungus. If that egg is not quickly removed then the fungus will spread and infect otherwise healthy eggs. All adjacent eggs may be killed.

Prevention of egg infection by fungus is achieved by adding methylene blue to the water immediately after the eggs have been spawned. Be careful not to overdose because eggs may suffer developmental problems. Also remove any off-white eggs with a pipette before they become heavily infected.

Cichlids actually do a good job in removing dead and unfertilised eggs and keeping the eggs free from dirt as part of their parental care.

Fungus treatment for fish

Treat as soon as possible. use an aquatic antifungal remedy from your local aquarium shop. Place any heavily infected fish in a quarantine tank and treat the fish there. In the main aquarium a dose of salt added to the water should heal slightly infected fish and help to kill of most spores present.

Prevention is better than cure and this is a mostly preventable illness. Remedy the environment of the aquarium that led to the original outbreak. If it was an accident such as a dead fish then a salt dose to the aquarium should be sufficient.

However, if the cause was rotten food then you must keep up good feeding practices of not feeding more than the fish will eat. Observe all the food you place into the aquarium and remove any uneaten food with a siphon. When your aquarium has a nitrite or an ammonia spike then fish will go off their food. If you feed at this time then you will surely cause a disaster.

Make sure your filter is fully cycled. Make sure that the water you add to the aquarium has the chlorine removed before adding. Also, siphon through and disturb the gravel to remove any build up of fish waste. And make sure your filter has not become clogged. If the filter is clogged then squeeze out the excess dirt from the sponge into a bucket of aquarium water.

And finally, keep up good maintenance practices. Then you should never have a problem with fungus again.
