生態學
; 淡水; 半鹹淡水 底中水層性. 熱帶; 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.
非洲: 在 Sabi , Lundi , Pungwe 與 Buzi 河的部份下游中的尚比西河下游與南方。
大小 / 重量 / 年齡
Maturity: Lm ?  range ? - ? cm
Max length : 35.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 2); 最大體重: 1.1 kg (Ref. 52193)
背棘 (總數): 16 - 18; 背的軟條 (總數): 10-13; 臀棘 3-4; 臀鰭軟條: 8 - 11; 脊椎骨: 29 - 31.
銀色到鐵-灰色的, 腹面略白的。 繁殖期的雄性在頭部與身體有咽喉與所有的鰭黑色上非常深灰色; 具有一個在背部上的紅色或橘色的邊緣而且在鰓蓋上具有一個灰色或黑色的大理石紋。
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).
偏愛靜止的池水,有雜草叢的地方。 曾經報告只從淡水與低海拔地區與緯度, 所以它的鹽度與容忍溫度是可能窄於 O. mossambicus 的.(參考文獻 2)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00827 - 0.04391), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
