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).
栖息于大的高地河川。 似乎避开静止的水域。 对于它的生物学特性所知极少。 像其他的本属的成员, 它可能主要捕食植物与偶然地在昆虫与昆虫幼生上.(参考文献 12693) 也报告在河中偏爱深水池与在洪水季节的时候回游进入溪流，运河与湖之内。 在大群鱼群中回游。 (参考文献 37770) 回游伴随着 Cosmochilus harmandi ， Cirrhinus spp。, 黑野鲮［Labeo chrysophekadion］ 与 Bangana sp.(参考文献 37770) 在市场上销售生鲜地了。 (参考文献 12693)
