簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 13 - 16; 背的軟條 (總數): 10-14; 臀棘 3; 臀鰭軟條: 8 - 10. Diagnosis: upper profile of head not convex; lower pharyngeal bone about as long as broad, and with anterior lamella shorter than toothed area; median pharyngeal teeth not broadened; dorsal fin with 14-16 spines and 10-14 soft rays (mean 15, 12); 8-11 lower gillrakers; dark longitudinal band appears on flanks when agitated; no bifurcated dark vertical bars on flanks; dorsal and caudal fins not or feebly blotched (Ref. 53405). Body brownish-olivaceous with an iridescent blue sheen; lips bright green (Ref. 34290, 53405). Chest pinkish (Ref. 34290). Dorsal, caudal and anal fins brownish-olivaceous with yellow spots, dorsal and anal fins outlined by narrow orange band; "tilapian" spot large, extending from last spine to 4th soft ray and always bordered by yellow band (Ref. 34290, 53405). Specimens 2-14 cm SL with completely yellowish or greyish caudal fin without dots, but tend to develop a greyish caudal fin with dots of increasing size during development; above 14 cm SL, this species has greyish caudal fins with dots on entire caudal fin (Ref. 57660).
橄欖色的有一個藍色虹彩的光輝; 唇明亮的綠色; 胸略帶桃色的。 二條水平的斑紋在身體與尾柄上越過六或七個黑的縱帶了。 背鰭、尾鰭與臀鰭橄欖色的有黃色斑點, 背鰭與臀鰭邊緣為一條狹窄的橘色條紋了。 尾鰭通常覆蓋著一個灰色的網絡有灰白的空隙。 成年的標本具有一個大的﹐黑色的﹐和幾乎圓形的斑點幾乎完全地黃色的邊緣。 (參考文獻 34290)

生物學特性     字彙 (例如 epibenthic)

Occasionally form schools; mainly diurnal. Prefer shallow, vegetated areas (Ref. 4967). Fry are common in marginal vegetation and juveniles are found in the seasonal floodplain. Herbivorous, feed on water plants and epiphyton, and some invertebrates. Substrate spawner (Ref. 28714). Larvae develop in close association with substrate. Extended temperature range 6.5 - 42.5 °C, natural temperature range 10.5 - 36°C (Ref. 3).

偶然地形成魚群; 主要日行性。 偏愛淺灘,有植物生長的區域。 (參考文獻 4967) 魚苗是常見於雜草叢,而且稚魚被發現於季節性的洪泛區。 食草的, 吃水中植物與灌木藻 , 與一些無脊椎動物。 底部產卵魚.(參考文獻 28714) 仔魚在靠近底部中發育。

Spawns in lake bottoms with pebbles or sand and abundant vegetation (Ref. 3). Lays adhesive eggs on the substratum which are guarded by both parents (Ref. 6298). Reported to deposit and guard eggs in shallow nest (Ref. 12069). Produces up to 1000 eggs (Ref. 1672).非洲與歐亞大陸: 摩洛哥南部,撒哈拉,塞內加爾河,尼日-貝努埃河的系統,薩桑德拉河與象牙海岸的 Bandama 河,佛塔河系統,查德河- 雪利河流域,烏班基河-偉萊河-Ituri 的河 (剛果) ,湖 Mobutu 與 Turkana, 尼羅河系統與 Jordan 系統。 引入後的一些國家報告不利的生態衝擊。
