Prefers clear, flowing waters of larger perennial rivers, frequenting pools below rocky rapids (Ref. 2801). Found also in quiet water with aquatic wed cover. Lives in shoals, usually in shallow water over sandy bottoms. It feeds on aquatic larvae and insects, shrimps and small crustaceans, from surface or water column (Ref. 13337, 52193). Breeds in spring and summer (Ref. 7248, 52193). Also caught with dip nets (Ref. 4967).
偏爱被在岩石的急流之下常常聚集于水池的较大的终年不断之河川的清澈又流动水域。 (参考文献 2801) 也发现于静止的水域了有水生生物覆盖的地方。 生活在浅滩, 通常在浅水区沙质底部之上。 吃水中幼生与昆虫，虾与小型甲壳动物。 (参考文献 13337) 繁殖于夏天。 (参考文献 7248) 也用抄网捕获。 (参考文献 4967)
