Description

The redeye labeo is a cyprinid of the family Cyprinidae reaching about 25 cm. The elongate, almost cylindrical body has conspicuously red eyes and an inferior sucker-mouth with fringed, horny lips, with which the fish scrapes algae and growth (aufwuchs) off stones. The species comes from eastern and southern Africa and lives in schools in clear, flowing rivers with stony bottoms. It grazes mainly algae and growth, supplemented with some detritus. In the rainy season it migrates upstream to spawn on gravel bars. Through its grazing it plays a role in the river ecosystem, and locally it is a valued food fish.
