Occurs in shoals and migrates upstream during spring and summer. Prefers warmer areas of rivers and often congregate at the inlets of small tributaries where the temperature is warmer than that of the main river. Feeds on algae, insect larvae and crabs. Spawns in fast-flowing stretches of rivers that are algae-free (Ref. 6465). Breeds in summer, migrates upstream and spawns over gravel beds. Males mature at about 10 cm FL, females at 15 cm FL (Ref. 7248, 52193).
出现于浅滩而且溯河回游在春天与夏天期间。 偏爱河的较热的区域而且时常在温度是超过主要河的小支流的小水湾聚集。 吃藻类，昆虫幼生与螃蟹。 产卵在河的快速流动支流那是无藻类.(参考文献 6465) 繁殖于夏天, 溯河回游而且产卵砾石床之上。 雄性在大约 10 公分 FL 时成熟, 雌性在 15 公分 FL.(参考文献 7248)
