Maturity: Lm ? range ? - ? cm
Max length : 3.3 cm TL 雄魚/尚未辨別雌雄; (Ref. 35237)
Lives in schools of about several dozen individuals, in muddy creeks or along the sandy-muddy edge of shallow estuarine zones. Sometimes stays motionless at the surface and prefers to seek shelter beneath floating plants. Fertilization is internal (Ref. 35237). Several days after fertilization, females lay eggs individually on aquatic plants. 7 cm male 8 cm female max TL (Ref. 026130, needs confirmation). Not a seasonal killifish (Ref. 27139).
生活在大約數十個個體的魚群, 在泥濘的小溪中或者沿著水淺河口的區域沙-泥濘邊緣。 有時停留不動在水表面而且偏愛在漂浮的植物之下尋找庇護所。 體內受精.(參考文獻 35237) 受精後的好幾天, 雌性在水生植物上個別地生下卵。 7 公分雄魚 8 公分雌性的最大 TL.(參考文獻 026130, 需要證實) 不是一個季節性的鱂科魚類.(參考文獻 27139)

1 - 2 eggs are visible through the transparent body of the female. Viviparity is facultative, as the eggs can be laid prematurely and be attached to plants (Ref. 35237).南美洲: 奧里諾科河到亞馬遜河,也就是, 委內瑞拉，蓋亞那，蘇利南，法屬圭亞那與巴西。
