The Kneriidae are a small family of freshwater gonorhynchiform fishes native to Africa.

They typically live in fast-flowing highland streams, and are small fish, no more than 15 centimetres (5.9 in) in length. Some species are sexually dimorphic, with the male possessing a rosette on the gill covers that is absent in the females. Other species are neotenic, retaining larval features into adulthood.[1]


There are about thirty species in four genera:[2]
