生态学
; 淡水; 半咸淡水 底中水层性. 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.

银色到铁-灰色的, 腹面略白的。 繁殖期的雄性在头部与身体有咽喉与所有的鳍黑色上非常深灰色; 具有一个在背部上的红色或橘色的边缘而且在鳃盖上具有一个灰色或黑色的大理石纹。
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).
偏爱静止的池水，有杂草丛的地方。 曾经报告只从淡水与低海拔地区与纬度, 所以它的盐度与容忍温度是可能窄于 O. mossambicus 的.(参考文献 2)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
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.
93245).
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (26 of 100).
