There are conflicting views
on the adult size of this species from 50 to 120cm
but whatever view you take this is a large and predatory
catfish that would need to be housed with larger tank
mates. Aquarium Care: Needs a large
tank over 4'0 in length as juvenile and maybe larger
as it grows into adulthood. It is territorial towards
conspecifics and similar fishes. Provide hiding places
with a large filtration capacity capable of handling
the high nitrogenous waste that it will produce. Diet:
live foods, earthworms, tablet, frozen and pellet
foods. This is a catfish for the experienced large
predatory catfish keeperand not
Amazon, Essequibo, Orinoco, and Paraná basins.
Type locality: Brasiliae fluviis.
