Lives in groups at the surface of small creeks with clear waters. Also found in ponds where it is found together with Rivulus (Ref. 27188). Feeds on Ephemeroptera larvae and ants. The spawned eggs are deposited on submerged leaves and are guarded by the males (Ref. 12225). During incubation, the male oxygenates the eggs (Ref. 27188).
小溪群居在水表面且水流清澈的地方。 也發現於池塘在那裡它被發現伴隨著 Rivulus.(參考文獻 27188) 吃蜉蝣仔魚與螞蟻。 魚卵被沈澱在水下的樹葉上面而且被由雄性保衛。 (參考文獻 12225) 在孵育的時候，雄魚給卵充氧氣。 (參考文獻 27188)
