The Penang betta (Betta pugnax) is a species of gourami native to Southeast Asia and common in swiftly flowing forest streams of the Malay Peninsula, Thailand, Sumatra, and the Riau Islands. In addition to its native range, the species has been introduced to Guam. It can be found amongst the vegetation growing along the banks. This species can reach a length of 6.7 centimetres (2.6 in) SL. It is one of the mouthbrooding Betta species. This species, as a natural predator of mosquito larvae, has found use in mosquito control efforts.Prior to its being eclipsed in Western public recognition by the mass-imported B. splendens (the Siamese fighting fish), B. pugnax was well known as a fighting fish, as denoted by the specific epithet of pugnax, attracting the interest of scientists studying animal behaviour at least as long ago as the 1880s.
