Identification Tips

1. 1

   Barbels

   Presence of two distinct pairs of barbels on the upper jaw, a key differentiator from many other cyprinids.

2. 2

   Dorsal Fin Spine

   The strong, serrated spine at the front of the dorsal fin is a characteristic feature.

3. 3

   Scale Size

   Relatively large, prominent scales, especially along the lateral line, which typically has 35-40 scales.

4. 4

   Mouth Position

   Subterminal mouth, adapted for bottom feeding, with thick, protrusible lips.

5. 5
