Usually found in ponds, ditches, slow flowing streams, both clear and turbid, in both open and shaded areas. A voracious species which feeds on small crustaceans, insects and mollusks (Ref. 12225). Gregarious and non-aggressive, it is reputedly easy to rear and to reproduce in the aquarium (Ref. 27188). Maximum length questionable (Ref. 38376).
通常發現於池塘，溝渠，緩慢流動的溪流,是既清澈的且混濁的,在開放而陰暗的區域中。 吃小型甲殼動物，昆蟲與軟體動物的一個狼吞虎嚥的種.(參考文獻 12225) 群居而非侵略性，它對後面一般認為容易與在水族館繁殖.(參考文獻 27188) 最大的長度可疑的.(參考文獻 38376)
