|Scientific Name:||Trichopodus leerii|
|Species Authority:||(Bleeker, 1851)|
Trichogaster leerii (Bleeker, 1852)
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Reviewer(s):||Kottelat, M. & Allen, D.|
The fish is popular in the aquarium trade, although most specimens in trade are thought be sourced from captive-bred sources. Populations in some parts of the species' range (especially in central Thailand, from where it may have been extirpated; C. Vidthayanon pers. comm. 2012) have declined in the past twenty years due to habitat loss and degradation as a result of peatland and wetland conversion and reclamation. Habitat management to conserve its habitat is urgently needed, and monitoring of the harvest for the ornamental trade is recommended. Levels of decline are expected to continue and may approach 30% across its range in the next 10-20 years, and the level of habitat loss is expected to continue. The species is assessed as Near Threatened as levels of population decline are suspected to nearly qualify the species as threatened under criteria A: population reduction.
|Range Description:||The species is known from the eastern side of the Malay Peninsula (southern Thailand and West Malaysia), and from Indonesia (Sumatra and Kalimantan; Roberts 1989). The species has been recorded from central Thailand (the lower Chao Phraya drainage around Bangkok; Bleeker 1865, Hora 1923, Smith 1945), however there are no recent records of the species from this area, and populations in central Thailand may have been extirpated (C. Vidthayanon pers. comm. 2012).|
Native:Indonesia (Kalimantan, Sumatera); Malaysia (Peninsular Malaysia); Thailand

|Population:||Populations of the species have much declined in some parts of the species' range (central Thailand, and possibly the Malay Peninsula) due to habitat loss and degradation as a result of peatland and wetland conversion and reclamation. Levels of decline are expected to continue and may approach 30% across its range in the next 10-20 years, and the level of habitat loss is expected to continue.|
|Habitat and Ecology:||Inhabits peat marshlands and swamps, and lowland flooded forests.|
|Use and Trade:||The species is popular in the aquarium trade, although it is thought that a significant proportion of the stock in trade is from captive-bred sources as wild specimens are very sensitive to transport, and therefore expensive.|
|Major Threat(s):||Habitat loss as a result of peatland conversion and wetland reclamation are the main threats, especially in central Thailand and the Malay Peninsula. Overfishing for the aquarium trade is a secondary threat.|
|Conservation Actions:||Habitat management is needed to conserve the species' habitat. Harvest monitoring for the ornamental trade is recommended.|
