Identification Tips

1. 1

   Caudal Peduncle Spot

   Look for the distinct, round to oval black spot on the caudal peduncle, just before the tail fin. This is a key identifying feature.

2. 2

   Barbels

   Observe the two pairs of barbels around the mouth. The maxillary barbels are noticeably longer than the rostral barbels.

3. 3

   Dorsal Fin Ray

   Note the strong, serrated last unbranched ray in the dorsal fin. This is characteristic of many Puntius species.

4. 4

   Body Shape and Coloration

   The elongated, silvery body with a generally plain coloration, apart from the caudal spot, helps distinguish it from other more colorful or patterned barbs.
