Description

The dark stonebasher is a small African elephantfish of the family Mormyridae from East Africa. The species grows to about 10 cm and has a stocky, dark body with a blunt snout. It prefers shallow mud-bottomed waters near shore vegetation such as papyrus and Vossia. Like other elephantfishes it generates weak electric fields to orient itself and communicate in turbid water. It feeds on aquatic insects, mainly midge larvae. Elephantfishes are known for their relatively large brains. The dark stonebasher is harmless to humans.
