Hemibagrus wyckioides is a species of catfish (order Siluriformes) of the family Bagridae.
Distribution
These catfish originate from the Mekong basin and are reported from Chao Phraya, Mae Klong and peninsular Thailand river systems.[1]
Appearance and anatomy
H. wyckioides reaches a length of 130 centimetres (51 inches) TL.[1] This species is the largest Bagrid catfish in Asia and may reach 80 kilograms.[2] The caudal fin is white when the fish is small, but it becomes bright red when it reaches about 15 cm (6 in).[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]
Ecology
H. 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 humans
This fish is marketed fresh as a food fish.[1] Hemibagrus are aquacultured in Asian countries.[3]
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 the Hell alone.[5]
