背棘 (总数) : 14 - 16; 背的软条 (总数) : 10 - 12; 臀棘: 3; 臀鳍软条: 8 - 11; 脊椎骨: 29. Diagnosis: 15-20 rakers on lower limb of first arch; 30-32 scales in lateral line (Ref. 81260). Body dark grey or green (Ref. 2, 81260). Head large, especially in adults (Ref. 2), its length 37-45% of standard length (Ref. 81260). Jaw teeth very small (Ref. 81260). Breeding males green; intense tilapia-mark present in young until about 10 cm SL, absent above 15 cm SL; as the gonads mature the lower parts of the head and the flanks become more metallic and green; most brooding females silver grey in general color; fins mainly of a neutral color; pelvic fins may be yellow (Ref. 2).
最显着的特徵是大的头部尤其当成鱼时。 繁殖期的雄性绿色。 一个密集吴郭鱼-标志直到大约 10 公分 SL 出现在幼鱼, 不存在上方 15 公分 SL。 当生殖腺成熟头部的下面部份，而且侧面变得更金属和更绿色的。 大多数的繁殖期的雌性银色的灰色大体上颜色。 鳍中性颜色主要是; 腹鳍可能是黄色。
Occasionally forms schools; is mainly diurnal; juveniles feed on mayfly larvae and various terrestrial insects among a diet in which animal items formed a high proportion (Ref. 2). Adults feed predominantly on phytoplankton (Ref. 2, 52307). Congregates in small groups (under 10 individuals) in open water regions and at a maximum depth of about 5 m (Ref. 52307). Lacks marked sexual dichromatism when sexually active (Ref. 81260). Ovophilic, maternal mouth brooder (Ref. 52307) that forms temporary pair bonds (Ref. 81260) prior to spawning, but none after (Ref. 52307). Ventures to regions near the edges of the lake for spawning, where the male constructs craters in the sand; males infrequently incubate the eggs (Ref. 52307).
偶然地形成鱼群; 主要日行性。 存在一个食性稚鱼吃孚游类仔鱼与各种不同的陆栖昆虫在那一个动物项目形成一个高的比例了。 成鱼主要以浮游植物为食。 (参考文献 2)
