Introduction

The Regal Angelfish is one of the most beautiful tropical marine fishes.

Identification

The Regal Angelfish can be recognised by the alternating yellow and black-edged white bars on the body. The soft part of the dorsal fin is blue with black scribbles. The anal fin has yellow and blue stripes. The caudal fin is yellow.

It has a strong preopercular spine that is characteristic of the Angelfish family Pomacanthidae

Juvenile Regal Angelfish are similar to the adults, but are more orange than yellow, and have a distinct ocellus on the soft dorsal fin.

Habitat

Regal Angelfish inhabit coral reefs and lagoons that have abundant coral growth. They are commonly found near caves and ledges. This fish is often seen in pairs or as solitary individuals and rarely in small groups. Juveniles are secretive, using coral crevices and cracks for shelter.

It is found in depths from 1 m to 48 m.

Distribution

It occurs in tropical marine waters of the Indo-West and Central Pacific, from East Africa and the Red Sea, north to Japan, south to Australia and east to the Tuamoto Islands.

In Australia it is known from the north-western coast of Western Australia around the tropical north of the country, and south to southern New South Wales.
