Prefers small and shallow streams or sunny swamps. A quite species which is not so keen on jumping (Ref. 35237). In its natural environment of shallow marshes and streams with little current, it can be sympatric with R. xiphidius, R. igneus, R. lungi and R. cladophorus. Not a seasonal killifish. Is easy to maintain in the aquarium (Ref. 27139). Sexual differentiation begins during the first week. Reproduction may start at around 10 months. Females spawn approximately 20 eggs measuring 1.5 mm diameter. Hatching occurs after 4 weeks of incubation at 22°C, thus releasing alevins measuring 3 mm long. This species is well known by the aquarists who breed them easily (Ref. 35237).
偏愛小的與淺的溪流或晴朗的沼澤。 一相當種是不是如此鋒利關於跳躍.(參考文獻 35237) 在它的水淺濕地與溪流的自然環境水流很少的地方, 它能被與 R. xiphidius ， R. igneus ， R. lungi 與 R. cladophorus 重疊分佈. 不是一個季節性的鱂科魚類。 容易在水族館維持。 (參考文獻 27139) 性的區別在第一個星期期間開始。 繁殖在大約 10個月可能開始。 大約雌性產卵 20個卵測量 1.5 mm 直徑。 在 4個星期的孵育之後在 22 °C 孵化, 如此釋放測量 3 mm 長的剛孵化的小魚。 這種是廣為人知藉由容易地繁殖他們的水族館.(參考文獻 35237)
