Max length : 9.8 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5723); common length : 3.8 cm TL 雄鱼/尚未辨别雌雄; (Ref. 12193); 最大年龄: 3.00 年 (Ref. 12193)
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).
栖息于小溪及小型到中型河川的水浅沙地急流与水道。 (参考文献 3814) 幼鱼与成鱼主要捕食 entomostracans(水蚤，桡脚类的动物与介形虫); 成鱼也啃食在晚上的蚊仔鱼 (宝刀鱼) 的逐渐增加数量。 生命期,3-4 年; 性成熟在第二个夏季或第一个夏季末达到了它生命中的。 二个产卵峰巅期, 较年长的个体在春季中旬产卵而且去年的幼鱼在七月产卵.(参考文献 10294)

Generation time: 1.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
