Gouramis, or gouramies, are a group of freshwater anabantiform fish that comprise the family Osphronemidae. The fish are native to Asia—from the Indian Subcontinent to Southeast Asia and northeasterly towards Korea. The name "gourami", of Indonesian origin, is also used for fish of the families Helostomatidae and Anabantidae.
Osphronemus is a genus of large gouramis, the only genus within the subfamily Osphroneminae. These fish are known as the giant gouramis and are native to rivers, lakes, pools, swamps and floodplains in Southeast Asia, with O. exodon from the Mekong basin, O. laticlavius and O. septemfasciatus from Borneo, while O. goramy is relatively widespread. O. goramy has been introduced outside its native range in Asia, Africa and Australia.
The snakeskin gourami is a species of gourami native to Southeast Asia. Prior to the merging of Belontidae to the family Osphronemidae, the snakeskin gourami was regarded as the largest member of its family. It is still the largest species in its genus and subfamily.
Trichopodus is a genus of tropical freshwater labyrinth fish of the gourami family found in Southeast Asia. Gouramis of the genus Trichopodus are closely related to those of Trichogaster ; species of both genera have long, thread-like pelvic fins used to sense the environment. However, Trichopodus species have shorter dorsal fin base and, when sexually mature, are much larger, with the largest, the snakeskin gourami, capable of reaching a length of over 8 in (20 cm).
The ornate paradisefish or spotted gourami, is a species of gourami endemic to Sri Lanka. It is the only recognized species in its genus.
Betta enisae is a species of gourami endemic to the Kapuas River basin of Indonesia. It is an inhabitant of forest streams with slightly acidic waters, and can mostly be found in the shallows amongst the leaf litter. This species grows to a length of 5.9 cm (2.3 in). It is commonly used as bait by local fishermen and has been found in the aquarium trade. The specific name of this fish honours Enis Widjanarti who assisted Kottelat in his expedition to the Kapuas Lakes.
Betta edithae is a species of gourami endemic to Indonesia where it occurs in Kalimantan, Sumatra and the Riau Archipelago. This species grows to a length of 8.2 cm (3.2 in), and can be found in the aquarium trade. The specific name honours the German aquarist Edith Korthaus (1923-1987), who co-discovered this species with her husband Walter Foersch. Walter is honoured in the specific name of another species they discovered, Betta foerschi.
Trichogaster fasciata, the banded gourami or striped gourami or Colisa or Kholshe, is a tropical labyrinth perch found in some Asian countries like Bangladesh, Eastern India, Northeastern India, Nepal, Upper Myanmar, China and Pakistan.
The elephant ear gourami is a large species of gourami native to the Mekong river basin in Thailand, Laos, and Cambodia.
The giant red tail gourami is a large species of gourami belonging to the family Osphronemidae. This endangered fish is native to the Southeast Asian island of Borneo, where only known from the Kinabatangan and Segama river basins in Sabah, East Malaysia. First described in 1992 based on an aquarium specimen, its exact range was not entirely certain, leading some source to incorrectly also report it from Indonesia.
The giant gourami is a species of large gourami native to freshwater habitats in Southeast Asia. It has also been introduced elsewhere. The species is commercially important as a food fish and is also farmed. It can be found in the aquarium trade, as well. The species has been used for weed control on highly invasive aquatic plants like Salvinia molesta, as the giant gourami can be a voracious herbivore.
The Anabantiformes, collectively known as Labyrinth fish. are an order of air-breathing freshwater ray-finned fish with two suborders, five families and having at least 207 species. In addition, some authorities expand the order to include the suborder Nandoidei, which includes three families - the Nandidae, Badidae and Pristolepididae - that appear to be closely related to the Anabantiformes. The order, and these three related families, are part of a monophyletic clade which is a sister clade to the Ovalentaria, the other orders in the clade being Synbranchiformes, Carangiformes, Istiophoriformes and Pleuronectiformes. This clade is sometimes referred to as the Carangaria but is left unnamed and unranked in Fishes of the World. This group of fish are found in Asia and Africa, with some species introduced in United States of America.
Luciocephalus aura, sometimes called the green-spotted pikehead or peppermint pikehead, is a species of freshwater ray-finned fish from the subfamily Luciocephalinae of the gourami family Osphronemidae. It is endemic to Sumatra where it has been recorded from the middle Batang Hari River and from the middle Musi River drainage. It is typically found in forested swamps. An undescribed similar taxon has been seen in central Kalimantan and this is possibly a third species in the genus Luciocephalus.
Trichopodus poptae is a species of ray-finned fish in the subfamily Luciocephalinae, part of the gourami family Osphronemidae. It is distinguished from its congeners by the faint, almost indiscernible patterning on the body apart from the black blotch at the base of the tail. This species is endemic to Kalimantan, the Indonesian part of the island of Borneo.
Betta ibanorum is a species of gourami endemic to southern Sarawak in Malaysia. The species name ibanorum was named after the Iban people, the largest group of people in the Sarawak. This species is a mouthbrooder, and grows to a length of 8.1 centimetres (3.2 in) SL.
The threestripe gourami, also known as the Mekong croaking gourami, is a species of freshwater ray-finned fish from the subfamily Macropodusinae which is part of the gourami family Osphronemidae. It is native to south-east Asia.
Betta obscura is a species of gourami that occurs in the Barito basin in Kalimantan Tengah, Indonesia. This species is a mouthbrooder, and grows to a length of around 9 centimetres (3.5 in) SL.
Betta midas is a species of gourami in the genus Betta. It is native to Asia, specifically the island of Borneo, where it occurs in the Kapuas River basin in West Kalimantan in Indonesia, as well as western Sarawak in Malaysia. It is typically found in acidic blackwater rivers in remnant and intact peat swamp forests. The species reaches 6.6 cm in standard length and is known to be a facultative air-breather.
Betta hendra is a species of gourami. It is native to Asia, where it occurs in the Sabangau River basin in Central Kalimantan on the island of Borneo in Indonesia. It is typically found among plants in peat swamp forests shaded by trees and bushes with a depth of 5 to 50 cm and no water current. Based on aquarium observations, the species forms bubble nests. The species reaches 4.2 cm in standard length and is known to be a facultative air-breather.
Betta lehi is a species of gourami. It is native to Asia, where it occurs in the area southwest of Kuching in Sarawak in Malaysia, as well as the lower Kapuas River basin in West Kalimantan in Indonesia. It is typically found among vegetation in quiet streams in peat swamp forests and other acidic wetland environments. The species reaches 6.1 cm in standard length and is known to be a facultative air-breather.
