Origin[edit | edit source]

Endemic to Australia. Present along both eastern and western Australian coasts, from Kirra in southern Queensland to Jervis Bay in New South Wales, and from Kingston in South Australia to the Houtman Abrolhos in Western Australia.

Sexing[edit | edit source]

Difficult to visually sex. Are not captive bred.

Tank compatibility[edit | edit source]

A large yet generally peaceful fish that should work with similar sized robust tank mates. As juveniles they don't seem to mind their own kind but adults prefer to be solitary. They will eat inverts however and are best in very large fish-only set ups.

Diet[edit | edit source]

Prefers meaty foods such as krill, shrimp etc.

Feeding regime[edit | edit source]

Feed once or twice a day.

Environment specifics[edit | edit source]

An inshore marine species which lives in shallow bays and sandy inlets near river mouths. Found most frequently over sand, rocks and weeds in clear to turbid waters. Needs a very large set up with large hiding places in rock work. They thrive best in marine set ups rather than brackish and tanks should be mature and well filtered.

Behaviour[edit | edit source]

A generally peaceful very large catfish that prefers to hide during the day.

Identification[edit | edit source]

A large bodied catfish with a broad head and 4 sets of barbels around the head. They have a fairly striking colouration, with dark brown base mottled with yellow/orange spots.
