(P. W. Fang & Chaux, 1949)
Appearance and anatomy
H. wyckioides reaches a length of 130 centimetres (50 in) TL. This species is the largest Bagrid catfish in Asia and may reach 80 kilograms. The caudal fin is white when the fish is small, but it becomes bright red when it reaches about 15 cm (6 in).
H. wyckioides occurs in large upland rivers and is common in areas with rocky bottoms and irregular depths. These fish do not migrate, but they reproduce locally and enter the flooded forest during high water in July–October. H. wyckiodies feed on insects, prawns, fish and crabs.
Relationship to humans
H. wyckioides and Hemibagrus wyckii are the two members of this genus imported as aquarium fish. This species will rearrange decorations in the aquarium. These fish are not picky and will eat a variety of fish foods. This species is sometimes claimed to be the most aggressive freshwater fish in the world, and should be kept alone.
