Distribution

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.

Appearance and anatomy

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]

Ecology

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]

Relationship to humans

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]
