Tank compatibility[edit]

A very large catfish that will eat anything small enough to fit into its mouth. Should be kept only with fish of similar size or larger. They are also a very aggressive species and will attack other tank mates and in majority cases kill them. They have been known to bully and kill other tank mates many times their own size. Other tank mates are highly not recommended and discouraged or should be done so with caution.


These large predatory catfish are carnivorous. They feed on worms, insects, and other fish. They are scavengers like 90% of catfishes and will readily take sinking pellets, worms, insects, live feeders, shrimp, and/or bite size cut fillets. They are not picky eaters.

Feeding regime[edit]

In the wild they hunt/feed through out the day. However, majority of their hunting/feeding is done during the night time.

Environment specifics[edit]

They are require a few good hiding places in driftwood.


They are extremely aggressive. They are most active during the night time and are loungers during the day. Though aggressive they have a unique personality.


A very large chunky catfish with a broad mouth. Olive/yellow in colour with a paler belly and brown fins, with long barbels. Can be mistaken for Zungaro zungaro.
