Ekologi
; sötvatten; brackvatten bentopelagisk. Tropical; 13°S - 28°S
Africa: Lower Zambezi and southwards in the lower parts of the Sabi, Lundi, Pungwe and Buzi Rivers (Ref. 5166); also Ruvuma River on the Tanzanian-Mozambique border; Lake Rutumba, Lupululu system, and the Lupuledi west of Lindi (Ref. 5166). Previously, two subspecies were recognized: Oreochromis placidus placidus and Oreohromis placidus ruvumae.
Size / Vikt / Age
Könsmognad: Lm ?  range ? - ? cm
Max length : 35.5 cm TL hane/ej könsbestämd; (Ref. 2); publicerad maxvikt: 1.1 kg (Ref. 52193)
Taggstrålar i ryggfenan (totalt) : 16 - 18; Mjukstrålar i ryggfenan (totalt) : 10 - 13; Taggstrålar i analfenan: 3 - 4; Mjukstrålar i analfenan: 8 - 11; Ryggkotor: 29 - 31.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Prefers quiet pools 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 narrower than those of O. mossambicus (Ref. 2).
