Occurs along the coastal zone and prefers water bodies with little current. Lives in groups. Feeds on worms, small insects, crustaceans and plants (Ref. 7020). The males are generally very much smaller and more svelte than the females. It is a very prolific species and its reproduction can easily be carried out in the aquarium (Ref. 12225). With an incubation temperature of 26°C, hatching of the eggs occurs within 48 to 60 hours (Ref. 27188). Maximum length questionable (Ref. 38376). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).
生存沿著海岸的區域而且偏愛水體水流很少的地方。 群居。 吃蠕蟲，小的昆蟲，甲殼動物與植物。 (參考文獻 7020) 雄性通常非常較小與更苗條的超過雌性。 它是一個非常多產的種與它的繁殖能容易地是在水族館成功完成.(參考文獻 12225) 有一個 26 °C 的孵育溫度, 卵的孵化在 48 到 60 小時裡面出現。 (參考文獻 27188) 最大的長度可疑的.(參考文獻 38376) 水族館保持: 形成 5個或更多個體的群體; 水族館最小體型 60 公分.(參考文獻 51539)
