What is bichir fish?

Bichir fish, also known as Polypterus, are a fascinating species of freshwater fish native to the rivers and lakes of Africa. They have a unique prehistoric appearance with a long, cylindrical body and a series of bony plates along their sides. Bichirs have primitive lungs that allow them to breathe air, in addition to gills, enabling them to survive in oxygen-poor environments.

Bichir fish are carnivorous and typically feed on a diet of small fish, crustaceans, and insects. They have a nocturnal feeding habit and are known to be voracious predators.

Bichirs are relatively hardy fish that can adapt to a wide range of water conditions, but they prefer a temperature range of 75-82°F and a pH level between 7.0-8.0. They are also known to be able to withstand low oxygen levels in the water due to their ability to breathe air.

Bichirs are not aggressive towards other fish, but they can become territorial as they grow older. They are best kept in a spacious aquarium with plenty of hiding spots and a sandy substrate to mimic their natural habitat.

Overall, bichir fish are unique and fascinating creatures that can make an interesting addition to a freshwater aquarium for experienced fish keepers.
