Purple Queenfish

Overview

The Purple Queenfish, also known as the Purple Anthias, is a vibrant, reef-associated species native to the Indo-West Pacific. These fish are typically found in large, hierarchical aggregations along the upper edges of drop-offs and steep outer reef slopes.

Distribution & habitat

This species is widely distributed across the Indo-West Pacific, ranging from Mauritius to the Philippines, Indonesia, the Solomon Islands, and as far south as the Great Barrier Reef and Rowley Shoals. They are also reported in Palau and southern Japan. They prefer current-rich environments on continental and outer reef slopes.

Appearance

This species exhibits distinct sexual dimorphism. Females are characterized by a deep purple to pinkish body with a prominent yellow stripe along the back that extends into the upper caudal fin lobe. Males are generally more uniform in purple coloration, featuring a dark blotch on the posterior dorsal fin, a more pointed snout, and a fleshy protuberance on the upper lip. Nuptial males may also display yellow jaws and possess significantly elongated caudal fin lobes.

Biology & behavior

These fish are diurnal and live in social groups organized by a strict hierarchy, typically consisting of a dominant male and a harem of females and juveniles. They are protogynous hermaphrodites, meaning they can change sex from female to male. While generally peaceful, they may occasionally display aggression toward other species.

Feeding

As carnivores, they feed primarily on zooplankton, including planktonic crustaceans and fish eggs, which they capture directly from the water column.
