在 2 与 13 公分 SL 之间的 几内亚非鲫〔Tilapia guineensis〕 有一个显示一个 bicolour 尾鳍的趋向, 是清澈的淡黄色的背面与深色的淡黄色的腹地; 在 13 公分 SL 上面的标本全部有 bicolour 尾鳍而且没有任何的点。 (参考文献 57660)
Very tolerant of elevated salinities, found in pure seawater, even reproduction in these highly saline environments is possible (Ref. 52307). Feeds on shrimps, bivalves, plankton (Ref. 28587), detritus (Ref. 28587, 52307), higher plants, algae, aufwuchs and small crustaceans (Ref. 52307). Oviparous (Ref. 205). Very prolific, spawning up to every 3 weeks (Ref. 52307). Pair bonding, open (Ref. 52307) substrate brooder/spawner (Ref. 52307, 81260) with both parents guarding the brood (Ref. 52307).
