生態學
; 淡水; 半鹹淡水 底中水層性; pH range: 6.0 - 7.0; 非遷移的; 深度上下限 20 - 80 m (Ref. 35237). 熱帶; 26°C - 30°C (Ref. 35237)
South America: French Guiana (Ref. 36579) and Suriname (Ref. 59052). Status of this species is uncertain; possibly a regional form of Rivulus urophthalmus.

Max length : 7.1 cm SL 雄魚/尚未辨別雌雄; (Ref. 101566)
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).
出現於被水淹沒的大草原，而且海岸的沼澤那是陽光照射的。 時常發現於淺水域而且除了 R. ocellatus 以外與法屬圭亞那的其他 Rivulus 重疊分佈了。 (參考文獻 27188) 不是一個季節性的鱂科魚類。 稚魚從測量 1.2 mm 的卵被釋放。 (參考文獻 35237) 性的區別在 4個月是可能的; 性成熟在 5個月的年齡被達成。 (參考文獻 27188) 平靜與無源; 容易在水族館維持。 (參考文獻 27139)
