Hemibagrus wyckii is a species of catfish ( order Siluriformes) of the family Bagridae. It is occasionally called the crystal-eyed catfish [1] or black devil catfish.[ citation needed]
This species originates in Asia from Thailand to Indonesia. [2] It is known from the Mekong [3] and Chao Phraya [3] drainages in central Indochina. It is also known from the Batang Hari [3] and Musi River [3] drainages in Sumatra, the Pahang River [3] and Perak River[ citation needed] drainage in Peninsular Malaysia, the Citarum [3] drainage in Java, and the Baram, [3] Rejang, [3] Kapuas, [3] and Barito River [3] drainages in Borneo.
Hemibagrus wyckii are black with a few white markings on the caudal and dorsal fins, and the eyes are sky blue. [4] They reach about 71 centimetres (28 in) SL. [2] The head is extremely depressed and broad. The caudal fin is dark grey. The dorsal fin spine has 10–12 serrations on the posterior edge. [3]
Hemibagrus 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. [3]
Hemibagrus wyckii appears to be restricted in the middle reaches of the large rivers it inhabits. [2] This species feeds on insects, prawns and fishes. [2] These fish are aggressive and can attack animals of their own size; they have been claimed to be the "only freshwater fish unafraid of man". [1] [4]
This fish is marketed fresh as a food fish. [2] Hemibagrus are aquacultured in Asian countries. [4]
Hemibagrus wyckii and Hemibagrus wyckioides are the two members of this genus imported as aquarium fish. [4] These fish will bite and can damage objects in the aquarium. [1] Due to both its aggressive and its predatory nature, this species should be kept alone. [1]
