Cichlid
Meet the bichir
Bichirs (Polypterus) are an ancient group of African freshwater fish with lungs, armored scales and a row of small dorsal finlets. The Senegal bichir (Polypterus senegalus) is the most common in stores and usually reaches about 12 inches. Larger species, such as P. endlicheri, can exceed 2 feet.
Tank setup
- A 75 gallon tank is a good home for a Senegal bichir. Large species need 125 gallons or more.
- Floor space matters more than height. Bichirs live on the bottom.
- They breathe air, so leave a gap between the water and the lid, and make sure the lid is secure. Bichirs are skilled escape artists.
- Use sand or smooth substrate and provide caves or driftwood.
Feeding
Bichirs are predators. Feed sinking carnivore pellets, frozen bloodworms, mysis, krill and earthworms. They hunt by smell and are often most active in dim light.
Tank mates
Any fish small enough to fit in a bichir’s mouth may be eaten, usually at night. Good mates are robust fish of similar or larger size. Avoid fin nippers.
Frequently asked questions

How big do Senegal bichirs get?
Most reach about 12 inches in aquariums.
Can bichirs live with cichlids?
Often yes, with similar sized, not overly aggressive cichlids. Very small cichlids may be eaten.
