Introduction To The Amazon Biotope Aquarium: Recreating The Amazon River
One of the more popular options when it comes to biotope selection is the Amazon biotope aquarium. This is a setup that is designed from the ground up to emulate the conditions of the Amazon River, and, if done right, will give you a unique insight into the ecology of this fascinating part of the world.
While keeping a biotope aquarium of a tropical river with such diversity may seem like an expert-level challenge, the truth is that beginners looking to set up their first Amazon biotope aquarium have little to fear if they do adequate research and make the right choices. If approached correctly, the Amazon River can be a very accessible biotope choice.
Getting started on your amazon biotope aquarium
Despite its apparent complexity, the Amazon River environment can be relatively simple to replicate. The key is making practical choices concerning the accuracy of your biotope aquarium: The Amazon River is full of undesirable predators, leeches, and parasites among many other qualities that are detrimental to the aquarium environment, so you will need to make some compromises.
These issues do not stop at aquatic predators, but go on to include dark, muddy water conditions that offer very little visibility and a thick soil bottom that would be impossible to clean. That will not only make your tank plant-less and barren due to the lack of light penetrating the water, but will also make it difficult for to you enjoy seeing your fish at all. In general, you are best advised to avoid trying to create a 100% faithful biotope aquarium.
You can, however, make great strides forward in your plans to keep an Amazon biotope aquarium if you combine some effective aquascaping with common sense ecological accuracy. The best way to do this is to scan the Internet for images of Amazon biotopes that you like the look of and then work towards your own expression of that example. Once you have a clear idea in mind, there are three basic methods to approaching your biotope aquarium:
• Find the fish that you like, determine what part of the Amazon River they are from, and then create the biotope to suit them;
• Choose a specific part of the Amazon River to replicate and fill your tank exclusively with fish from that area;
• Begin with the plants, driftwood, and substrate and then build your tank upwards from there.
Either one of these methods can produce a successful Amazon River biotope aquarium if handled correctly. You need only choose which elements you are most comfortable starting with.
Types of amazon biotopes
Since the Amazon River is so large, there are a number of options from which you can choose when it comes to your specific type of tank. Some biotope options will be very different from others, and more ideally suited to certain species that would naturally live there. A short list of options include:
• Whitewater Stream—This environment features water with a slightly muddy appearance. Whitewater tanks look their best with driftwood and dead branches added in, as well as a dark sand substrate.
• Blackwater Stream—Waters that originate deep within the rainforest and contain a high level of dissolved leaf litter are usually referred to as blackwater streams. This water is more acidic due to the dissolved leaf litter that you will need to add, or even use as a substrate.
• Oxbow Lake—This refers to the many crescent-shaped lakes that form when the Amazon River changes course. These lakes tend to be both muddy and filled with accumulated leaf litter and debris. For this reason, mud is an ideal substrate, and Oxbow biotope keepers will want to keep filtration to a minimum.
How to simulate amazon river water
The acidity of your Amazon biotope aquarium will vary depending on which of the three above choices you choose for your tank. For example, a whitewater river environment will require water with a pH level between 6,3 and 7,0, while a blackwater biotope will be more acidic—between 4,5 and 6,5, and the Oxbow Lake water has a pH between 5,4 and 6,8.
The temperatures of the various forms of the Amazon biotope aquarium tend to be less varied, with 24-28° C being the norm. Water hardness should be kept reasonably low, as most of the dissolved materials in Amazon waters are not mineral, but organic: a dH level between 3-8 should be ideal.
When it comes to attaining the signature colouration of Amazon water and keeping the fish as comfortable as they would be in the wild, it is necessary to mix peat with your reverse osmosis-filtered water as well as some leaves to give it substance. Examples of leaves that will help create the tannic water commonly seen in the Amazon are:
• Indian almond leaves,
• Oak leaves,
• Copper beach leaves.
The idea is to stain the water using these leaves in order to give it the unique brown appearance that every Amazon biotope should have to some degree. The other main element of your biotope water will be peat.
Peat is widely available from aquarium supply stores and fish shops and is necessary for gaining the correct level of dissolved organic matter in the water and reproducing the Amazon River environment correctly. In order to maximize the benefits of peat, it is recommended that you do not use with activated carbon filtration or with waterborne fish medicine.
Peat is a unique element of the Amazon river environment and one part of your biotope that cannot be skipped. Your Amazon biotope aquarium tank should be cycled with peat present, and topped off if the water gets too clear after changing later on.
Populating your amazon biotope aquarium
The Amazon River is home to an enormous number of different species, and some of them are better suited to certain tanks than others. Naturally, you will want to choose species that do not prey on one another and that can live in relative peace and harmony in your tank—this can be tricky when it comes to Amazon fish.
One of the main aspects that you will want to take into consideration is the size of your tank. If you plan on keeping a small tank, then basing your Amazon biotope aquarium on a population of tetras or dwarf cichlids would be a great idea, while larger tanks can afford to support more exotic options.
If you have a large enough tank, you can populate your tank with Angelfish, Silver Dollars, or even piranhas. Care must be taken with larger community tanks keeping these kinds of fish, as most of them are very aggressive. Often, aquarists will stick to a single species in order to minimize violence between fish—and even then the tank is not guaranteed to be 100% violence-free.
Considering plants for your tank
Plants, too, must be considered in light of the unique water conditions that the Amazon River provides. The main issue here is that the standard water conditions of the Amazon offer very little light penetration. Some flexibility on your plant choices here can help a great deal in the long run. Some plants that would be at home in this biotope would be:
• Echinodorus (Amazon Sword, Dwarf Sword, etc.);
• Hair Grass;
One of the major concerns for plants in an Amazon biotope aquarium is access to light. If your water features a high level of dissolved organic material like it should, your plants might not have adequate access to regular aquarium lights, requiring you to get more powerful ones for them. Cabomba and Myriophyllum plants, in particular, can present problems from this point of view.
Another concern when it comes to aquarium plants in this environment is the number of plants to keep. That level of dissolved organic material in the water will make algae control a challenge—keeping lots of plants will help balance your tank and keep it relatively clear. Again, if you choose to be flexible in your plant choices, you can benefit from a healthier aquarium even if it is not 100% faithful.
Aquascaping and driftwood
While you may have all the information you need to begin your new Amazon aquarium, creating a natural-looking Amazon river environment requires that you take the time to plan your tank out carefully and find the right décor for it.
Driftwood is an essential element of a faithful Amazon biotope aquarium tank. If you have a larger tank and would like to keep one or two panaque catfish, you may even need to provide driftwood as food for the fish. Trying to source natural driftwood from the actual Amazon River is a futile task for most aquarists in the world—instead, you will have to find suitable wood from other sources.
In general, clean bog hardwood that has been carefully dried out can be used in your aquarium. You will want to introduce the wood before the plants and fish in order to compensate for any water quality issues that may occur.
Putting together your tank with all of these separate elements will take some planning and forethought. If you have taken the time to look at other aquarists’ Amazon biotopes, you might have a good idea of where you want to go with yours. Another option it to find genuine photographs of the Amazon river and to use the materials at hand to replicate the aquascape to the best of your ability. Both of these are equally suitable methods of making an ideal Amazon biotope aquarium.
When you have completed your aquarium it is worthwhile going back to the original images to see how closely you have replicated the original biotope image. Perhaps you have surpassed the original and can relax. Or, perhaps you have forgotten some element that would add the finishing touches. When all is complete you can then sit back and enjoy your small simulation of the amazon river. After all this is what all the effort is all about.
