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.
