The fiveband barb (Desmopuntius pentazona) is a species of cyprinid freshwater fish from Southeast Asia. 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. pentazona.
The fish superficially resembles the tiger barb (Puntigrus tetrazona), except that there are five black vertical bands on an orange or gold body instead of four bands on the tiger barb. The fish will grow to a maximum length of TL.
