Summary:
A pelagic schooling fish found only in southern Australia. Adult males are bluish with a black bar on the side. Females are pinkish with a blue line below the eye. Small juveniles are pink to pinkish-orange with a dark mauve head.

Barber Perch form large schools on sheltered coastal reefs, where they feed on plankton above rocky reefs, outcrops and drop-offs. The closely-related  Butterfly Perch usually occurs in more exposed habitats on deeper reefs.
