Adults inhabit lakes and pools and runs of medium to large rivers. They are most common in clear water over sand or gravel. Form schools (Ref. 1998). Move to the surface at dusk to feed on microcrustaceans, midge larvae, and algae; descend to deeper waters at daybreak (Ref. 1998). They are preyed upon by birds (gulls, terns, mergansers, cormorants) and fishes (Ref. 1998). Oviparous (Ref. 205).
成魚棲息於中型到大型河川的湖與水潭與急流。 清澈的水域在沙地或礫石上面常見於。 形成魚群。 (參考文獻 1998) 在薄暮移動到表面覓食小型甲殼類動物,蚊仔魚與藻類; 在黎明對較深的水域下降。 (參考文獻 1998) 被鳥 (鷗,燕鷗,秋沙鴨, 水老鴉) 與魚捕食。 (參考文獻 1998) 卵生的.(參考文獻 205)
