Maturity: Lm ? range ? - ? cm
Max length : 8.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 27139); 8.0 cm TL (female); 最大年齡: 4 年 (Ref. 59043)
背棘 (總數) : 0; 背的軟條 (總數) : 10 - 11; 臀棘: 0; 臀鰭軟條: 12 - 14. Diagnosed from other species of Valenciidae, Fundulidae and Cyprinodontidae in Europe by the following characters: male with caudal yellow to orange, with reddish-brown posterior margin; spots organized into 4-7 vertical rows; dorsal and anal fins of adult males reaching caudal fin; 28-29 scales in midlateral series on body; anal fin usually with 12-13 rays; pectoral fin with 13-14 rays; male bluish to greyish, with numerous very narrow darker bars, not always distinct anteriorly, iridescent spots absent (Ref. 59043).
A short-lived species. Adults are found in swamps, lagoons, springs and associated wetlands and other water bodies with little current and plenty of vegetation (Ref. 30578). They feed mainly on crustaceans and insect larvae (Ref. 59043). Threatened due to habitat destruction, water abstraction, pollution (Ref. 26100) and competition with the introduced Gambusia holbrooki (Ref. 59043). The first toothcarp in the German aquarium trade. Not a seasonal killifish. Difficult to maintain in aquarium (Ref. 27139).
在德國水族貿易中的第一個 toothcarp。 一種生命期短的種是發現於沼澤，潟湖，泉水與相連的窪地與其他的水體水流很少的地方而許多植物。 (參考文獻 30578) 吃無脊椎動物。 受到威脅的由於棲息地破壞，水資源減少與污染.(參考文獻 26100) 不是一個季節性的鱂科魚類。 在水族館是難以維持。 (參考文獻 27139)
