生物学特性     字汇 (例如 epibenthic)

Found near the surface and among weeds in which it seeks refuge and food (Ref. 5595). Prefers standing or gently flowing water as in river backwaters, floodplains (Ref. 7248), swamps (Ref. 7248, 47311), creeks and pools (Ref. 47311). Usually found in small shoals near the surface, among fringing vegetation; usually abundant when present (Ref. 47311, 52193). It feeds on small invertebrates like mosquito larvae and daphnia (Ref. 52193). A serial spawner, laying eggs which attach to vegetation (Ref. 52193). When food is abundant, breeding occurs daily over an extended period (year-round where conditions are suitable) (Ref. 7248, 52193). 6 cm max TL (Ref. 3788). Not a seasonal killifish. Is difficult to maintain in aquarium (Ref. 27139).

发现于靠近表面了与在杂草之中在它寻找藏身处与食物.(参考文献 5595) 偏爱持续或逐渐地流动水当在河洄水区,洪泛区与沼泽中。 通常发现于小的浅滩。 吃像蚊虫幼生与水蚤的小型无脊椎动物。 一只连续的产卵鱼,生下吸附到植物的卵。 当食物很丰富的时候,繁殖每日出现经过一长段时间 (全年环境是适当的地方) 。 (参考文献 7248) 6 公分最大 TL.(参考文献 3788) 不是一个季节性的鱂科鱼类。 在水族馆是难以维持。 (参考文献 27139)
