Feeding saltwater fish

Different fish have different diets

Saltwater fish food is not as easy to get right as for freshwater fish. Depending on the type of marine fish you have, they will have different feeding needs. There are the seafood eaters who will require bits of fish or seafood tidbits. Then there are the plankton feeders who need to be fed with small foods such as baby brine shrimp, frozen cyclops and mysis shrimp. plankton feeders will need to be fed many times a day. If you supplement their diet with pellets these will have to be crumbled into the tank so that they can pick up the pieces.

Then there there are fish that feed on plant life such as seaweed and will need to be fed with greens from the kitchen and algae. And finally there are the algae grazers who will need a diet that is mostly algae. All vegetarian food will try to eat throughout the day so food must be made available throughout the day for them.

Your first job is to find out what your particular fish eats then set about buying or obtaining the foods they need. Some fish will not readily take to dried foods so you will have to rely on live foods and plant matter.

Some fish such as blennies are bottom feeders and search for organisms through the mulm at the bottom of the aquarium. They may feed off uneaten food left by other fish. Take care to see that these types of fish get properly fed. You may need to feed them directly with sinking pellets for them to find.

The fish that eat meat and that includes carnivores and omnivores will eat most forms of seafood from your fishmongers such as sea fish, prawns, mussels. Always chop these up into bite size pieces. For fish like tangs the pieces need to be very small because they tend to eat small life forms. Always blanch the seafood in boiling water for 1 minute to kill off any potential sea borne parasite.

Various recommended saltwater fish foods

Algae sheets such as nori which is a japanese food available in delicatessans is a great food to feed saltwater algae eating fish. When it is placed in the aquarium you will see all the vegetarian fish go into a feeding frenzy for it. It contains many essential micro-nutrients that are not available within garden greens such as romaine lettuce and spinach. So must be provided as a supplement.

All fish in the wild eat live food or fresh vegetable matter. Many wild caught fish will not take to dried foods so must be fed live foods such as brine shrimp and algae. However, many fish can be persuaded to eat chopped vegetables such as romaine lettuce and other greens. Dip the leaves into boiling water for 1 minute so that they become soft. Seaweed in the sea is usually soft so softening greens will simulate seaweed texture.

Some saltwater fish may take dried foods or even frozen foods. You can soak the defrosted frozen foods or dried foods in a multivitamin supplement for saltwater fish. This will ensure that your fish will get any vitamins that may be lacking in the diet you provide.

Frozen saltwater fish foods are available such as krill, mysis shrimp or cyclops. These should be defrosted thoroughly before being fed to the fish. If your fish take to this then your job will be much easier. But there is no reason to not also supplement their diet with seafood scraps from the supermarket or fishmonger.

Dried foods are not really recommended because of the lack of essential micronutrients that is available in live and fresh food. On saying that some fish keepers do get away with it. As long as you soak the dried food in a good quality saltwater fish vitamin supplement and top up their diet with some seafood tidbits and algae then you should be able to get away with feeding dried food. With dried foods you need to be extra vigilant and remove any scraps of food that fall to the floor and remain uneaten at the bottom of your aquarium.

Make your own saltwater fish food

If you can set up a small saltwater algae tank on a sunny window spot then great. Your algae eating fish can eat fresh organic algae, the perfect food that they would find in the wild. When doing a water change or just removing water from the main aquarium, do not throw it away but use it to top up your algae tank. The algae will grow well from the fish manure. If you can get some small shrimps or other minute invertebrates growing in the algae aquarium then all the better. Your omnivorous fish will love the tidbits of livefood found in the algae.

Place sheet rocks in the algae aquarium so that algae can attach itself. Then move these rocks to the main aquarium for feeding. When the algae has been stripped away move the rocks back to the algae aquarium.

Growing Brine shrimp or other shrimp in a hatchery

You can hatch out and grow brine shrimp in a separate small tank. Use a sponge filter powered by an air pump. Keep the water heated up to 80F. The tank should be placed on a sunny window sill. Pour in your brine shrimp eggs and wait for them to hatch. After hatching they take a days to eat off their yolk sacs so should not be fed immediately. Feed the shrimp with yeast, wheat flour, soybean powder, or egg yolk. Do regular water changes to keep the tank clean. The salinity for brine shrimp should by at 1.018 specific gravity. If you look after the shrimp well then they should grow and breed providing you with a continuous supply of shrimps. Gut loading the brine shrimp before feeding your fish is a good idea. This is just means feeding vitamin rich nutritious food to the brine shrimp for a couple of days before you feed your fish.

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.

 How to reap the benefits of aquarium live food rearing for your fish

If you have spent great amounts of time and effort reproducing a natural habitat for the fish in your tank, yet you still feed them commercially prepared fish food, it might be a good time to consider rearing live food. There are numerous benefits to rearing your own sources of live food, covered in the points below:

• Live food more closely reproduces the natural diet of fish, making them healthier and happier.

• Live food, being composed of living organisms, will not decay in your tank if left uneaten the way that fish flake does.

• Adult fish that are used to foraging for their food behave more actively in pursuing live food than prepared fish flakes.

• Better nutrition can be achieved through indirect enrichment— feeding your live food vitamin supplements that get passed on to your fish.

• Live food encourages breeding, and some species of fish will not breed successfully without it.

For young fry live food rearing is essential:

• Most species of fish give birth to fry that are too small to eat commercially prepared foods.

• Many species of young fish fry will only eat food that is moving, and need to be carefully weaned onto non-moving food over time.

• Live food is the healthiest option for young fry, and will help them grow faster and become healthy adults.

Types of live food

There is a huge range of live food available at your local fish store or online but this can be seasonal. Choosing which of the available types of live food you should use depends greatly on the species of fish you keep and whether you are feeding adult fish, fry, or both.

For adult fish, there are a number of attractive and healthy aquarium live food choices available. These largely consist of water fleas, various worms and larvae, as well as some shrimp. Some of the most popular species are:

• Daphnia. These tiny water fleas often top the list of easily managed aquarium live food rearing options. They live comfortably in slightly alkaline freshwater tanks with temperatures between 18-25 degrees Celsius and medium light intensity. Daphnia multiply quickly, offer beneficial vitamins for your fish, and are very easy to raise.

• Blood Worms. Blood worms are widely available from a vast majority of fish stores and bait shops, and offer a very convenient live food for your fish. They are simple to raise and once the life cycle is introduced, greatly reduce the need to supplement your fish’s diets with other foods.

• Earth Worms. Earth worms offer one of the most complete food sources available for aquarium live food rearing. They are high in protein, essential vitamins, and roughage. They do require soil, however, and can grow quite large, making them ideal for larger fish in larger tanks.

• Mosquito Larvae. Mosquito larvae are some of the easiest aquarium live food rearing options, since they will readily grow in just about any environment where you have access to stagnant water and sun. You must be very careful, however, to regularly harvest the larvae before they turn into troublesome adult mosquitoes.

• Brine Shrimp. Brine shrimp are an excellent and highly popular live food option for fish. They are especially suited to this purpose since baby brine fish are also suitable for fish fry thanks to their tiny size and nutritional value.

• White Worms. These nutritious worms are easy to cultivate and fish love them. They are high in fat as well as protein and can stay alive in the water for days. These worms can make your fish fat, however, so care should be exercised so as not to overfeed them.

Any of the options listed above should be enough for most species of adult fish, but fish fry have more subtle nutritional needs. If you are raising young fish fry, you will need to give them food small enough for them to eat and nutritious enough for them to subsist on completely, such as:

• Infusoria. This term refers to a number of extremely tiny microorganisms that serve as a readily cultivated source of food for your fry. It can be convenient to think of Infusoria as fresh water plankton. Infusoria are easy to culture and widely available online or at your local aquarium store.

• Brine Shrimp. One of the most popular and successful aquarium live food rearing options for young fry, baby brine shrimp are simple to cultivate and small enough for some fry to feed on.

• Microworms. These hardy creatures can thrive in a wide variety of environments, and make an excellent live food choice when you need a readily available source of food quickly. They can be cultivated in days and offer a complete source of nutrition that fry will gladly eat.

In many cases, offering your fish a variety of these food sources will help give them a varied and complete diet. Many of these foods are complementary when added together, and can be combined for the optimal balance of nutrients, vitamins, and essential proteins.

How to cultivate live food for your aquarium

If you are interested in aquarium live food rearing for your fish, you will need to invest some effort in making a cultivation tank or water barrel to raise your food in. Most species of live food are very easy to raise and require very little attendance or care.

For instance, Daphnia can be cultivated in any large container with access to sunshine and green water algae or yeast. Optimal water conditions include a pH between 6.0 and 8.2 and a 20% water change every two weeks. With a large enough surface area for the water in the container, aeration is not even necessary.

Brine shrimp make a similarly easy aquarium live food rearing selection for fish keeping enthusiasts and do not even require a large container. They are filter feeders that need only be provided with a food source such as yeast or wheat flour, an air stone for aeration, and regular water changes.

Mosquito larvae are even simpler, readily growing in just about any pot of stagnant water with access to sunlight and algae. Mosquitoes will readily begin spawning anywhere they find the right conditions, and you need only net the larvae every few days to feed your fish.

Most of the worm species available at your local fish store can be raised conveniently in plant soil and introduced to your aquarium when they grow to full size. Cultures are simple to purchase and cultivate; once ready, they can be tossed directly into the aquarium.

Tips for easier growing of live food

Once you decide to begin investing in an aquarium live food rearing setup, there are a few important considerations that can help you make the most of your breeding. One of the most helpful ways to ensure sufficient stocks of food for your fish is to stagger multiple cultivars several days apart.

Keeping several separate tanks can help insure your aquarium live food rearing attempt from being compromised by disease or other problems. Just like a fish tank, any number of unwanted conditions could erupt in a live food cultivation environment, and you want to be protected against the possibility of losing your fish’s primary food source.

Depending on the specific needs of your fish, you may also be able to feed them essential vitamins and minerals through the live food you raise. This process is called indirect enrichment and can help you more effectively fight disease by ensuring the right combination of ingredients makes its way into your fish’s diet. Many fish supply sites provide aquarium live food rearing supplements like these.
