Spotted Hampala Barb

About

Found across the Mekong basin, Hampala dispar is a cyprinid that occupies a surprisingly wide range of habitats in the wild, from slow-moving lowland waters and reservoirs to the rapid mountain streams of the middle Mekong. Compared to its larger relative H. macrolepidota, it is the more practical aquarium option, reaching a more modest adult size while sharing much of the same character. Identification is reasonably straightforward: adults carry a single dark blotch on the body rather than a full vertical band, and the dark edging on the caudal-fin lobes is present but less sharply defined. Juveniles can look quite similar to young H. macrolepidota, with the body blotch more vertically extended and banding across the caudal peduncle that softens with age. In the aquarium, this species feeds on crustaceans and insect larvae primarily, using suction to take prey rather than lunging bites, and is generally peaceful toward anything it cannot fit in its mouth. That said, it is a powerful, fast fish, and timid or slow companions tend to lose out at feeding time. Keeping a group of five or more is important, as smaller groups tend to produce either a stressed subordinate or an unsettled lone fish. Robust, similarly-sized cyprinids, catfishes, and larger loaches make the most sensible companions. Breeding in captivity has not been documented.
