Very territorial. Also shows a hierarchical social structure (Ref. 35237). Occurs in stagnant waters where the current is slow and the substrate is thickly covered with dead leaves. Adults inhabit slow streams while most juveniles are found in scattered pools (Ref. 35237). Sympatric with other Rivulus spp. (Ref. 27188). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139). Hundreds of eggs, measuring 2.8 mm, are released during spawning and are subject to 3 months of diapause stage if required by local conditions. Hatching occurs after 2 to 3 weeks (Ref. 35237).
非常具有领域性。 也显示阶层的社会结构。 (参考文献 35237) 出现于水流慢的污浊的水域与底部是覆盖着厚的枯叶地方。 当大多数的稚鱼被发现于分散的水池时候，成鱼栖息于慢的溪流。 (参考文献 35237) 与其他的 Rivulus spp 重叠分布了。 (参考文献 27188). 不是一个季节性的鱂科鱼类。 在水族馆非常难以维持。 (参考文献 27139) 数以百计卵,测量 2.8 mm, 在产卵的时候被释放与是受 3个月的 diapause 阶段支配如果藉着地方环境需要。 在 2 到 3个星期之后孵化。 (参考文献 35237)
