gourami(go͞orä`mē), tropical freshwater fish of the labyrinth fish suborder. Like other members of that suborder, gouramis have a labyrinthine breathing apparatus connected to each gill chamber that enables them to utilize atmospheric oxygen. They can therefore live in oxygen-poor water. Gouramis are native to SE Asia and Africa. The true gourami, Osphronemus goramy, reaches a length of 2 ft (60 cm). It originated in Indonesia, but has been introduced in China and S Asia, where it is cultivated as an important food fish. Certain smaller members of the family, popular as aquarium fishes, are also called gouramis, but the best known, the white, 10-in.(25-cm) long kissing gourami (Helostoma temmincki) is now classified in the family Helostomatidae. Other popular gouramis are the moonlight gourami (Trichogaster microlepis) of Thailand, a 6-in. (15-cm) long, silvery-blue fish with long, threadlike ventral fins, and other Trichogaster species. The talking, or croaking, gourami (Trichopsis vittatus), a 2-in. (5-cm) long fish, is noted for the curious sounds produced by the males when they surface for air at night. The labyrinth fishes also include the bettabetta

(Osphronemus goramy), a fish of the suborder Anabantoidei of the order Percomorphi. With a body reaching a length of 60 cm, it has a bright and attractive coloration. The pelvic fins have one stiff spine and five soft rays, the first of which is a long supple filament that serves as a tactile organ. The gourami feeds mostly on aquatic plants. It builds a simple egg-shaped nest from air bubbles and plants, where it deposits its eggs. Its natural area of distribution is the Malay archipelago; however, it has been introduced into India, China, Africa, and Australia. The gourami is widely cultivated in ponds. Its flesh is very tasty. The pearl and three-spot gourami, which belong to the genus Trychogaster, are aquarium fish.
