Also known as the Malayan Halfbeak, Wrestling Halfbeaks are named for their elongated lower jaws. The “wrestling” portion of the name is derived from the tendency of the males of this species to fight, locking jaws with each other as they do. Some countries use this species as fighting fish, forcing males of the species to spar by keeping them in close quarters. These fish are found throughout portions of India, Myanmar, Laos, Thailand and Cambodia as well as other parts of south-eastern Asia. Wrestling Halfbeaks tend to inhabit slow-flowing waters such as canals, rivers, ditches and flooded fields. During the rainy season they can also be found in semi-brackish environments such as mangrove swamps.
