Description
Black body with white scale centres gives a regular spotted pattern. Has a broad, light edged black band down face over the eye, and an orange blotch on the edge of the anal fin. Black rather than red tail base distinguishes it from C. collare, an Indian Ocean species not known from Australia (not shown).
