Most types of Knifefish usually hide inside a cave during the day and come out at night to hunt for small fish. The African Knifefish is very hardy and not too aggressive, but will eat fish it can swallow.
Like all Knifefish they have a very interesting method of swimming by undulating the fin across the bottom of their bodies. If you want to try a Knifefish, the African Knifefish is the best type of Knifefish to start with, because they don't get huge like the Clown Knife, and they aren't delicate like the Transparent Knife, or too aggressive like the Carapo Knife. The African Knifefish is a a very good aquarium fish.

African Knifefish are very hardy and not as aggressive as most other Knifefish. They're interesting to watch swim. These Knifefish are somewhat nocturnal, so they need a cave or pipe as a home during the day. They are usually active at night, searching for food.

They may not bother small fish during the day, but then eat them at night. African Knifefish are members of a group of fishes called notopterids. Click here to read a brief article from the Encyclopedia Britannica about this group of fish.
