Introduction

The Potato Rockcod can grow to an alarming 2m in length, with a weight of about 100kg. In some areas it was common for divers to feed these large fish and this practice has resulted in some individuals boldly approaching divers underwater.

Habitat

It is found on coral reefs.

Distribution

It occurs throughout Indo-West Pacific.

In Australia it is known from off north-western Western Australia and the Great Barrier Reef. It's recorded as far south as Moreton Bay, Queensland.
