Bestämningsnycklar | Morfologi | Morfometri
This species is distinguished by the following characters: lateral line usually complete (15-37 pored scales, mode 35); barbels are conspicuous, not surpassing the vertical through middle of eye; circumpeduncular scales (14-16, mode 14) (Ref. 124213).
Cross section: oval.
This species has been recorded in a wide range of habitats, from clear flowing mountain streams with rocky substrates to mainstem sections of rivers and man-made impoundments with high water turbidity and fine substrates. It is likely to be omnivorous, as reported for other congeners, feeding mainly on insects, zooplankton, seeds, green algae and diatoms (Ref.124213).
