The fiveband barb (Desmopuntius pentazona) is a species of cyprinid freshwater fish from Southeast Asia.

[1][2] This species is restricted to blackwater streams and peat swamps in northwestern Borneo and possibly Peninsular Malaysia, but it has often been confused (especially in the aquarium trade) with the more widespread, closely related D. hexazona, which is similar except that it lacks the black spot at the rear base of the dorsal fin seen in D.

[2] Fiveband barbs are egg-scatterers that spawn among a coarse gravel bed in open water.

The fiveband barb is a harmless, active schooling fish that is usually kept in groups of 5 or more.

They prefer a well planted environment with rocks and driftwood but still need plenty of space to school.
