Écologie
; eau douce; saumâtre benthopélagique; profondeur 1 - ? m (Ref. 5723). Tropical; 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).

Maturity: Lm ?  range ? - ? cm
Max length : 44.0 cm SL mâle / non sexé; (Ref. 4967)
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).
