It is widespread in Southeast Asia.[1][2] It grows to {{convert|25|cm|abbr=on}} total length.[2] DescriptionAs its name suggests, the species does not have a barbel. There is a black blotch at the caudal base and rows of black spots along the scale rows. It grows to {{convert|25|cm|abbr=on}} total length.[2] A study from Borneo found that {{convert|8.1|cm|abbr=on}} standard length was reached at the age of two years.[3] HabitatBeardless barb inhabits a range of freshwater environments: rivers, lowland swamps, marshlands (in flooding time), lakes, and reservoirs. It is a migratory species that enters flooded areas during the high-water season.[1][2] DistributionThe species is found in the Mainland Southeast Asia (Myanmar, Thailand, Cambodia, Laos, Vietnam, Malaysia), including the Mekong and Chao Phraya basins, and in the Maritime Southeast Asia (Singapore, Malaysia, Indonesia), including the islands of Sumatra and Borneo.[1] UtilizationBeardless barb is present in local food fisheries. It is also present in the ornamental fish trade.[1] References1. ^1 2 3 4 {{cite journal | author = Vidthayanon, C. | title = Cyclocheilichthys apogon | journal = IUCN Red List of Threatened Species | volume= 2012 | page = e.T181284A1717065 | year = 2012 | doi = 10.2305/IUCN.UK.2012-1.RLTS.T181284A1717065.en }} {{Taxonbar|from=Q3233557}}2. ^1 2 3 {{FishBase |genus=Cyclocheilichthys |species=apogon |month=October |year=2015}} 3. ^{{cite journal|last1=Watson|first1=Dwight J.|last2=Balon|first2=Eugene K. |year=1985 |title=Determination of age and growth in stream fishes of northern Borneo |journal=Environmental Biology of Fishes |volume=13 |issue=1 |pages=59–70 |doi=10.1007/BF00004856}} 12 : Cyclocheilichthys|Barbs (fish)|Fish of the Mekong Basin|Fish of Cambodia|Freshwater fish of Indonesia|Fish of Laos|Freshwater fish of Malaysia|Fish of Myanmar|Fish of Singapore|Fish of Thailand|Fish of Vietnam|Fish described in 1842 |
