Inhabit shallow sandy riffles and raceways of creeks and small to medium rivers (Ref. 3814, 10294). Young and adult feed mainly on entomostracans (cladocerans, copepods, and ostracods); with adults also consuming increasing numbers of midge larvae (chironomids) at night. Life span, 3-4 years; sexual maturity reached in the second or late in the first summer of its life. Two spawning peaks, older individuals in the mid-spring spawning and the preceding year's young during the July spawning (Ref. 10294).
棲息於小溪及小型到中型河川的水淺沙地急流與水道。 (參考文獻 3814,10294) 幼魚與成魚主要捕食 entomostracans(水蚤,橈腳類的動物與介形蟲); 成魚也啃食在晚上的蚊仔魚 (寶刀魚) 的逐漸增加數量。 生命期, 3-4 年; 性成熟在第二個夏季或第一個夏季末達到.它生命中的。 二個產卵峰巔期, 較年長的個體在春季中旬產卵而且去年的幼魚在七月產卵.(參考文獻 10294)
