Oreochromis placidus

Black tilapia

Oreochromis placidus is a freshwater, benthopelagic fish. It lives in tropical waters of Africa: in the lower Zambezi and in the lower parts of the Sabi, Lundi, Pungwe and Buzi Rivers. Also in the Ruvuma River, in Lake Rutumba, Lupululu system, and the Lupuledi. It is native to the Idunda River .

This fish prefers quiet pools of water with marginal vegetation. It has been reported only from fresh water and low altitudes and latitudes, so that its salinity and temperature tolerances are probably lower. Previously, two subspecies were recognized, that is, Oreochromis placidus placidus and Oreochromis placidus ruvumae.
