In Australia recorded from around Geraldton in Western Australia north to the Timor Sea, from the northern Great Barrier Reef south to southern New South Wales and including Lord Howe Island.

Vivid colouration makes it easy to identify adults. Difficult to approach and constantly move across the substrate where they feed on small crustaceans and other invertebrates. Adults may be solitary while juveniles often in small groups, sometimes with juvenile Stethojulis sp. Juveniles pictured in top photograph. Grows to 22cm.
