Barb (puntimachh) name for some freshwater fish species of the family Cyprinidae, order Cypriniformes. Ten species of barbs under two genera Puntius (9 species) and Oreichthys (1 species) are found in Bangladesh. The moderate to deeply compressed body of this fish is silvery to greenish silvery or reddish brown in colour. Spots, blotches, bands on the body, and 4, 2 or no barbels are important identifying characters. Body length varies from 5 cm to about 20 cm.

The genus Puntius and Oreichthys have the following species: (a) Rosy Barb (P. conchonius)- body silvery, dark along the back; scales with dark bases; body deeper and flatter than other barbs; attains a length of about 10 cm; barbels absent. There is a large black spot on the side above the posterior portion of the anal fin. In the breeding season some individuals exhibit red and purple colour on the sides. Lateral line incomplete. (b) Chola Barb (P. chola)- Silvery body, attains a length of about 12 cm. Dorsal part more convex than that of abdomen; maxillary barbels one pair. There is a dark blotch on the side of the tail, a black blotch at the base of the 2nd to 5th ray of the dorsal and one to two rows of dark spots along its centre. In the breeding season males develop a red band along the side from the end of the opercle to the forked end of the caudal fin. Lateral line complete. (c) Golden Barb (P. gelius)- Reddish brown body moderately compressed, attains a length of about 13 cm.
