Identification Tips

1. 1

   Coloration

   Look for the characteristic rosy-red to orange body color in males, especially during breeding. Females are more subdued, silvery-gold.

2. 2

   Black Spot

   A prominent, round black spot on the caudal peduncle (the narrow part of the body before the tail fin) is a key identifier.

3. 3

   Absence of Barbels

   Unlike many other barb species, Puntius conchonius lacks barbels around its mouth, which helps distinguish it from similar-looking species.

4. 4

   Body Shape

   Its laterally compressed, somewhat deep body shape is typical of many barb species.
