|Scientific Name:||Acantopsis choirorhynchos|
|Species Authority:||(Bleeker, 1854)|
|Taxonomic Notes:||Given that the taxonomy/geographic diversity of the group is quite poorly studied, and that populations from Sabah (Malaysian Borneo), Manipur (India) and Thailand have been described to science (as A. octoactinotos, A. multistigmatus and A. thiemmedhi, respectively) quite recently it would seem likely that additional new species would result from any detailed study. It is probable that the species represents a cluster of undescribed species (Seriously Fish 2011).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Allen, D. & Smith, K.|
A widespread species with no known major widespread threats, it is considered Least Concern at present, however the species is in need of taxonomic revision and it should be reassessed when this is undertaken.
|Range Description:||The species was described from the confluence of the Lamatang and Enim rivers, Palambang Province, Sumatra, Indonesia. The species has an apparently large distribution extending across the majority of Indochina and beyond, including records from Malaysia (Peninsular and Borneo), Thailand, Myanmar, northeastern India, southern China, Viet Nam and Lao PDR (Talwar and Jhingran 1991; Seriously Fish 2011). In southeast Asia, the species is known from the Chao Phraya and Mekong basins.|

|Population:||No information available.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Inhabits swift, clear streams with sandy or gravelly bottom; also found in large rivers; burrows into the bottom and enters flooded fields (Talwar and Jhingran 1991). Found in the basin-wide mainstream of the lower Mekong. The general colour and marking serve to afford the fish concealment in clear, shallow, sandy streams (Pantalu 1986).
Acantopsis species are near-exclusive inhabitants of flowing river channels with substrates of sand, fine gravel or mud but are known to migrate into temporarily flooded zones during the wet months of the year (Seriously Fish 2011).
|Movement patterns:||Full Migrant|
|Use and Trade:||Found in fisheries, and of some interest as an aquarium fish.|
|Major Threat(s):||No information available.|
|Conservation Actions:||Research is required to confirm the taxonomic position of sub-populations.|
