Relevant Information:

Dorsal fin, short based with a spine and six rays. Pectoral fin with a spine and 13 rays. Anal fin has 14 rays. The adipose fin is moderately long but well separated from the dorsal and caudal fin. The caudal fin is forked with the upper lobe longer and more pointed than the lower lobe. Aquarium Care: Very much a catfish for the larger aquarium to be kept by the more serious catfish keeper. As with most species in this genera it will be predatory so would need to be kept with fish that are not too small although this species would be better to be kept on its own as other fish will be seen as prey. A large tank would be needed no smaller than 2 metres (6ft) long and a depth of 70cm (28ins) with powerful filtration, to give it plenty of swimming space. Diet: Earthworms, fish fillets, frozen foods such as whole and unbroken smelts, shrimp or mussel meat. Tablet and pellet foods will also be taken.

Common Name:
