Ecología
; agua dulce; salobre bentopelágico. 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.
Tamaño / Peso / Edad
Madurez: Lm ?  range ? - ? cm
Max length : 35.5 cm TL macho / no sexado; (Ref. 2); peso máximo publicado: 1.1 kg (Ref. 52193)
Espinas dorsales (total) : 16 - 18; Radios blandos dorsales (total) : 10 - 13; Espinas anales: 3 - 4; Radios blandos anales: 8 - 11; Vértebra: 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).
