Inhabits pools and deeper flowing stretches of larger tributary streams and mainstreams. Feeds on detritus and small organisms, usually taken from the bottom. Breeds in summer. Fry and juveniles form large shoals, adults occur in small groups. Due to the development of towns, agriculture and industry, the habitat of the species has been destroyed. Populations have also been eliminated by introduced predatory fishes (Ref. 7248).
棲息於較大的支流與主流的潭水與深水流。 吃碎屑與小的生物, 通常取自了底部。 繁殖於夏天。 魚苗與稚魚形成大群魚群, 成魚出現在小群魚群。 由於城鎮的發展, 農業與工業,此魚種的棲息地已經被破壞。 族群也已經被引入掠食性的魚消滅。 (參考文獻 7248)
