Leptobarbus melanotaenia, or the Bornean Sultan Fish, is a species of ray-finned fish in the genus Leptobarbus. It occurs in freshwater basins in Borneo. This species is a preferred food fish to be caught by local communities.[1]
The standard body length is 34 cm, but sexual maturity can be reached at 29 cm. The distinguishing feature of the species is the occurrence of a black mid-lateral line running along the lateral line, similar to L. rubripinna. However, unlike L. rubripinna, this black line does not fade or disappear as the fish reaches maturity.
They feed primarily on aquatic plants, leaf litter, fallen fruit, and seeds.[2]
