}} Hemibagrus wyckioides (Asian redtail catfish) is a species of catfish (order Siluriformes) of the family Bagridae. DistributionThese catfish originate from the Mekong basin and are reported from Chao Phraya, Mae Klong and peninsular Thailand river systems.[1] Appearance and anatomyH. wyckioides reaches a length of {{convert|130|cm|in|abbr=off}} TL.[1] This species is the largest Bagrid catfish in Asia and may reach 80 kilograms.[3] The caudal fin is white when the fish is small, but it becomes bright red when it reaches about {{convert|15|cm|in|round=0.5|abbr=on}}.[1]H. wyckii bears a resemblance to H. wyckioides, however H. wyckioides lacks serrations on the dorsal fin spine, has a shorter dorsal fin base, and shorter maxillary barbels.[2]EcologyH. wyckioides occurs in large upland rivers and is common in areas with rocky bottoms and irregular depths.[1][2] These fish do not migrate, but they reproduce locally and enter the flooded forest during high water in July–October.[2] H. wyckiodies feed on insects, prawns, fish and crabs.[2]Relationship to humansThis fish is marketed fresh as a food fish.[1] Hemibagrus are aquacultured in Asian countries.[11] H. wyckioides and Hemibagrus wyckii are the two members of this genus imported as aquarium fish.[3] This species will rearrange decorations in the aquarium.[4] These fish are not picky and will eat a variety of fish foods.[4] This species is sometimes claimed to be the most aggressive freshwater fish in the world and should be left alone.[5]See also
