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).
非常具有領域性。 也顯示階層的社會結構。 (參考文獻 35237) 出現於水流慢的污濁的水域與底部是覆蓋著厚的枯葉地方。 當大多數的稚魚被發現於分散的水池時候，成魚棲息於慢的溪流。 (參考文獻 35237) 與其他的 Rivulus spp 重疊分佈了。 (參考文獻 27188). 不是一個季節性的鱂科魚類。 在水族館非常難以維持。 (參考文獻 27139) 數以百計卵,測量 2.8 mm, 在產卵的時候被釋放與是受 3個月的 diapause 階段支配如果藉著地方環境需要。 在 2 到 3個星期之後孵化。 (參考文獻 35237)
