简单描述 检索表 | 型态特徵 | 形态测量图

Identified by the black spot found on the base of the dorsal fin; some specimens with thin transverse bands along the body but this may be attributed to the coloration before or after the reproductive period (Ref. 26543).
鉴定特徵为被发现于背鳍基底的黑色的斑点了; 一些标本有细的横纹沿着身体，但是这可能是归因于颜色在生殖的时期前后.(参考文献 26543)

生物学特性     字汇 (例如 epibenthic)

Feeds on algae and insects end up in the water (Ref. 26543). Tolerates extreme temperature, salinity and anoxia conditions (Ref. 26543). There was a proposal to use this species as biological control against mosquito larvae (Ref. 26543).

吃藻类，而且昆虫在水结束。 (参考文献 26543) 容忍极端的温度，盐度与缺氧环境。 (参考文献 26543) 有一个提案以这种作为对抗蚊虫幼生的生物学的控制。 (参考文献 26543)
