背棘 (总数) : 2; 背的软条 (总数) : 7 - 9; 臀棘: 2 - 3; 臀鳍软条: 16 - 19. Can be easily confused with Micralestes acutidens but has a more slender body with no black tip to the dorsal fin. Does not possess a pair of conical teeth behind row of teeth in lower jaw as in M. acutidens.
可能是与容易地互相混淆的 Micralestes acutidens 但是有一个更细长的身体有没有黑色的对背鳍的顶端。 在下颌中没有齿的一对锥形齿在后列当在 M. acutidens 中.
Shoals in shallow, vegetated marginal and floodplain habitats. Appears to prefer a swampy environment to open water (Ref. 13337). Feeds on small aquatic insects and other invertebrates. A partial spawner, breeding during high-water periods (Ref. 7248). Known to migrate up rivers and on to floodplains during flood season (Ref. 13337).
游入被植物生长的浅滩边缘的与洪泛区栖息地。 似乎喜欢沼泽的环境胜过开放水域。 (参考文献 13337) 吃小的水生昆虫与其他的无脊椎动物。 被繁殖在高水位期间时期的一个在局部时间产卵的鱼类.(参考文献 7248) 已知向上洄游到河与到洪泛区之上在洪水季节的时候.(参考文献 13337)
