African Knifefish
Couldn't load pickup availability
Not beautiful, but rare and unusual, the African knifefish has large eyes, barbs, and a long, thin, light chocolate body. Wild-caught in Nigeria, they are quite hardy and prefer live or frozen blood worms and similar food. These guys like to school in the wild, and if you have three in your fish tank they will always stick together.

Care Guide
Tank setup: Give them plants, driftwood and tubes or caves to hide in, plus dim lighting. They are most active at night.
Feeding: Feed frozen foods like bloodworms and brine shrimp once a day. Some learn to take sinking pellets.
Tankmates: They are shy and peaceful, so keep them with calm community fish too large to fit in their mouth.
Good to know: African knifefish can make soft barking sounds and swim backward as easily as forward.
