Head length 33.0-38.4% of standard length; jaw teeth with slender shafts and broad crowns (Ref. 81260). Mature fishes of both sexes with variable black areas on lower jaw and lower parts of head; no tilapia-mark (Ref. 2).
银灰色; 侧面中央的黑色斑纹在尾柄的前部上中断。 两性的成熟鱼在下颌与头部下半部上有多变的黑色区域。 没有吴郭鱼-标志。

生物学特性     字汇 (例如 epibenthic)

Found throughout the lake, but seems to prefer zones with submerged wooden or stone structures (Ref. 52307). Usually forms schools at the surface; feeds mainly on epiphytic and epilithic filamentous algae, and the diatoms, rhizopods, rotifers and organic debris found among them; adults feed by opening their mouths very wide and applying them to the surface of the rock as though sucking the material in (Ref. 2). Lacks marked sexual dichromatism when sexually active (Ref. 81260). Both sexes are possible incubators (Ref. 52307). Forms temporary pair bonds (Ref. 81260), for the entire duration of incubation/broodcare (Ref. 52307).

通常形成鱼群在水表面。 主要吃附生植物而附在岩石上的菌丝藻,而且硅藻,根足类动物, 轮虫与有机的残砾发现于他们中了。 好像吸材料进入,成鱼藉着非常广阔地打开他们的嘴和应用他们到岩石的表面觅食。 (参考文献 2)
