Diagnosis: upper profile of head strongly convex; lower pharyngeal bone about as long as broad, and with anterior lamella shorter than toothed area (Ref. 53405). 10 or fewer rakers on lower limb of first arch; unpaired fins not predominantly red-brown; mouth terminal; 29-30 scales on lateral line; outer row teeth robust (Ref. 81260). Dorsal fin with 14-16 spines and 12-13 soft rays (total rays 27-29) (Ref. 53405, 81260). Anal fin with 3 spines and 8-10 soft rays; caudal fin weakly covered with scales at base or entirely membranous (Ref. 81260). Caudal without spots, grey on upper lobe, yellow on lower; large vertical stripes weakly pronounced on flanks; flank scales with a blackish mark at base (Ref. 53405, 81260).

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).

Oviparous (Ref. 205). Subtrate guarding of eggs as a form of parental care is done by both male and female (Ref. 50828).非洲: 沿岸水域, 從塞內加爾河口到 Cuanza 河 (安哥拉)口.

Estimates based on models
Preferred temperature (Ref.
123201): 25.5 - 28, mean 27.4 °C (based on 152 cells).
Phylogenetic diversity index (Ref.
