最後單一的臀鰭鰭條 osseus 而且在後部地鋸齒狀的; 淡橘色臀鰭、腹鰭與背鰭; 最後的單一背鰭鰭條當成魚時與具有 28-36個鋸齒 (在標本 6-15 公分 SL 中) 達到尾鰭;(參考文獻 27732) 鋸齒狀的臀鰭硬棘; 銀色的身體顏色.(參考文獻 12693)
Inhabits large upland rivers. Seems to avoid standing water. Little is known about its biology. Like other members of the genus, it probably feeds mainly on plant matter and occasionally on insects and insect larvae (Ref. 12693). Also reported to prefer deep pools in the river and to migrate into streams, canals and lakes during the flood season. Migrates in large schools (Ref. 37770). Migrates together with Cosmochilus harmandi, Cirrhinus spp., Labeo chrysophekadion and Bangana sp (Ref. 37770). Marketed fresh (Ref. 12693).
棲息於大的高地河川。 似乎避開靜止的水域。 對於它的生物學特性所知極少。 像其他的本屬的成員, 它可能主要捕食植物與偶然地在昆蟲與昆蟲幼生上.(參考文獻 12693) 也報告在河中偏愛深水池與在洪水季節的時候迴游進入溪流，運河與湖之內。 在大群魚群中迴游。 (參考文獻 37770) 迴游伴隨著 Cosmochilus harmandi ， Cirrhinus spp。, 黑野鯪〔Labeo chrysophekadion〕 與 Bangana sp.(參考文獻 37770) 在市場上銷售生鮮地了。 (參考文獻 12693)
