; 淡水; 半鹹淡水 底中水層性; 深度上下限 1 - ? m (Ref. 5723). 熱帶; 22°C - 28°C (Ref. 2059); 5°S - 10°S
Africa: most of the Rufiji River and its tributaries, Kingani [= Ruvu] River, Mbwenkuru River and Wami River, all in Tanzania (Ref. 2, 118630, 118638). Populations in Zanzibar and Pemba may be native, although there may also have been some stocking from the mainland (Ref. 118638).
非洲: Rufigi 河與它的支流; Kilombero 與大的 Ruaha 河, 但是不在三角州中; Kingani 與 Mbenkuru 河, 所有的在坦尚尼亞。

A maternal mouthbrooder (Ref. 118638); oviparous (Ref. 205). A large, fast-growing species heavily exploited in its native range (Ref. 118638). It was globally cultured in the past, making use of its salt tolerance and ability to produce all-male strains through hybridisation with Oreochromis niloticus and O. mossambicus (Ref. 118638).
出現於溫暖的雜草叢生的溝渠與管。 (參考文獻 5723) 卵生的.(參考文獻 205)
