Features of a biotope aquarium

Biotope aquarium

A biotope is a mimicry of the natural habitat of aqua pets. How they live there, how they interact there, and many other things. There are many considerable things that you have to see before setting up a biotope aquarium. Here in the following, you will learn about the salient features of a biotope aquarium.

1. Plants

Research that are the plants in your desired biotope region. If the plants are available, then what kind of flora is present? It’s necessary to use similar flora in your aquarium.

2. Rocks

The other major step for setting up is to collect information about the surface. Is it a rocky region for which you want to create a biotope? It’s an excellent option to use stone as a bedrock or background rock to set up natural habitat.

3. Water

Water is the foremost thing to be considered while setting up a biotope. Consider the water parameters of the desired biotope region, i.e., pH, temperature, and water hardness. The volume of water you want to add depends on the size of the tank.

4. Substrate

The substrate is also a variable feature among different types of biotopes. A variety of substrates are available that you can use in the fish tank, i.e., gravel, sand, wood, stones, and branches. You can use these substrates with varying concentrations.

5. Lighting

It is another worth considering factor. Installing a planted aquarium light can help to replace the sunlight in your biotope, some light even can show the color of the fish and improve plant growth.

6. Fish tank

Last but not least, a fish tank is the most significant factor in setting up a biotope. It depends upon the size of the biotope that you want to replace.

How to set up a tropical biotope aquarium?

Biotope aquarium

Tropical areas are riched with multiple fish species and versatile biotopes. It’s interesting to set up a tropical freshwater biotope aquarium,  although it requires numerous considerations. Here in the following, you will find some popular types of biotopes and how to set up a biotope aquarium for them.

1. African River Rapids

The rapid region is part of the zaire watershed. The zaire river almost extends up to 200 miles in the Rapid area. It is the inspiration of many aquarists to create a biotope aquarium. Here are some key aspects that you should consider while setting up the rapid region biotope aquarium.

  • Plants

The rapid region is famous for its strong water currents. Due to strong water currents, it’s almost impossible for plants to grow in such water conditions. A few plant species can survive in high water currents, i.e., African Water Fern and Anubias. So, if your aquarium is well anchored, you can grow them into your aquarium.

African Water Fern

  • Aqua pets

There are very well-known species that are the inhabitant of rapid region biotopes. You can stock Eutropiellus, Distichodus, Synodontis, Steatocranus, Teleogramma, and Lamprologus in your fish tank. But keep in mind, select the peaceful and unique size fish species among them.

Distichodus

  • Water

Water currents are very high means that water is well-oxygenated. Keep pH between 7.0 to 7.5, water hardness between 6 to 10 dH, and a water temperature between 77oF to 81oF.

  • Tank

It’s necessary to provide them with ample swimming space. Therefore, set up the bio in a relatively large aquarium, i.e., a 75-gallon fish tank.

  • Tank accessories

The rapid region is famous for its high water currents. Water currents create turbulence in the water. This means that the water is well-oxygenated. Therefore, your aquarium should be well-aerated. For proper air circulation, use a powerful circulating pump in your aquarium.

  • Substrate

Use a few rocks in the aquarium to give a natural touch to your biotope. Sand and gravel are the most suitable substrates for the rapid region biotope tank.

2. Southeast Asian River

Southeast Asia is another famous tropical region of the world. It’s also a house of numerous fish species. It’s interesting to develop a biotope of the Southeast Asian river region.

  • Plants

These are the plain areas where the water speed drops to its extreme limit. Therefore, the biotope is densely populated with multiple plant species. You can grow the following plant species in your fish tank Crinum, Ceratopteris, Hygrophila, Cryptocoryne, and Nymphaea.

Hygrophila

  • Aqua pets

Tropical regions are full of breathtaking fish colors. So, it’s amazing to set up a Southeast Asian river biotope aquarium. You can stock the following types of fish Loaches, Barbs, Danios, Cyprinid sharks (Red-tail, Bala, etc.), Pangasius catfish [suitable only for extra large tanks], small Asian catfish, and Knifefish. But keep in mind that stock is always the same size fish.

  • Tank

Make sure that your tank has enough hiding spaces for your biotope inhabitants. You can use whatever fish tank instead of nano.

  • Tank accessories

Use the water circulation pump, which creates little surface turbulence for the exact match to their natural habitat. Use peat filtration to clean the water.

  • Substrate

Add fine gravel or clay as a substrate in your fish tank. Also, make it thickly planted.

Conclusion

Biotope aquariums consist of species that live and interact in the same environment. It is different from traditional aquariums and requires extra care and maintenance. Multiple ideas are there to set up a biotope aquarium, i.e., Swamp aquarium, Savannah biotope aquarium, River biotope aquarium, Jungle biotope aquarium, rocky reef biotope aquarium, and Lake biotope aquarium. Plants, rocks, water parameters, type of substrate, lighting, and size of the aquarium are the points to consider while setting up a biotope aquarium. African River Rapids, Southeast Asian River, Indian/Burmese River, and Southeast Asian Blackwater Pool are popular tropical biotopes among aquarists.
