Bichirs are living fossils belonging to the Polypteridae family. They are a sister family of ray-finned fishes that have developed similar characteristics such as a pair of functional lungs and the Ampullae of Lorenzini (organs that can sense electricity, also known as electroreceptors).
Bichirs are predatory fish, with a moderately aggressive temperament. They are problematic when kept with smaller size fish, as they will nip at their fins or even eat them. However, they seem to have no problems sharing their tank with larger fish.
These fish are bottom-dwellers and will spend most of their time near the bottom of the tank. They are nocturnal animals and prefer feeding during the night. They have poor eyesight and rely mainly on their other senses to find food.
They are quite large and sturdy fish that require specific water parameters and large tanks.
- They prefer softer waters
- Temperature 72-82°F
- Neutral pH (between 6.5-7.5)
Tank substrate is an important choice. Gravel can be an option, however, is not usually found in their natural environment. Sand is the best option.
They are not too fused about tank decoration, so you can add anything you prefer. Plants can be very useful, as they provide cover from light.
