Occurs in flooded savannas and coastal swamps which are sunlit. Frequently found in shallow waters and is sympatric with other Rivulus of French Guiana except R. ocellatus (Ref. 27188). Not a seasonal killifish. Juveniles are released from eggs measuring 1.2 mm (Ref. 35237). Sexual differentiation is possible at 4 months; sexual maturity is reached at 5 months of age (Ref. 27188). Calm and passive; is easy to maintain in the aquarium (Ref. 27139).
出现于被水淹没的大草原,而且海岸的沼泽那是阳光照射的。 时常发现于浅水域而且除了 R. ocellatus 以外与法属圭亚那的其他 Rivulus 重叠分布了。 (参考文献 27188) 不是一个季节性的鱂科鱼类。 稚鱼从测量 1.2 mm 的卵被释放。 (参考文献 35237) 性的区别在 4个月是可能的; 性成熟在 5个月的年龄被达成。 (参考文献 27188) 平静与无源; 容易在水族馆维持。 (参考文献 27139)
