Zenarchopteridae

Zenarchopteridae, the viviparous halfbeaks, is a family of ray-finned fishes in the order Beloniformes. The Zenarchopteridae exhibit strong sexual dimorphism, practicing internal fertilisation, and in some cases ovoviviparous or viviparous (the family also includes oviparous species). The members in the family are mainly found in fresh and brackish water of tropical Asia and New Guinea, but the genus Zenarchopterus also includes marine species from the Indo-Pacific. Several, such as the wrestling halfbeak, have become commonly traded aquarium fish.

Dermogenys is a genus of viviparous halfbeaks. They are widely distributed in fresh and brackish water in South and Southeast Asia, ranging from India to the Philippines and Greater Sundas. They are all viviparous, producing small clutches of up to 30 fry that closely resemble the adults, except they are much smaller, around in length. Adults are typically around in length, with females being slightly larger than males. Males tend to be more brightly coloured and are well known for being aggressive towards one another. The wrestling halfbeak, D. pusilla, is widely used in Asia as fighting anim

Hemirhamphodon is a genus of viviparous halfbeak fish. Most recognized species are endemic to lowland forest streams, rivers and swamps in Borneo (often in areas with peat), but H. phaiosoma and H. pogonognathus are also found elsewhere in Southeast Asia. The largest species reaches about in length. These fish are viviparous (with the exception of oviparious H. tengah) and are sometimes kept as aquarium fish, but otherwise have no commercial value.
