The bluering angelfish can be found in the Indo-West Pacific oceans from East Africa, throughout Indonesia and New Guinea to New Caledonia, north to southern Japan. Bluering angelfishes inhabit coastal rocky coral reefs and may be also encountered in caves or on wrecks, at depths of 3–30 m (9.8–98.4 ft). Bluering angelfish have adults which are mainly yellow with the body marked with obvious arcing blue lines and a blue circle shaped mark above the operculum. They frequently have an elongated tip to the dorsal fin and they have a white caudal fin with a yellow margin. They also have a pair of blue stripes across the face, one runs through the eye and the second is situated immediately beneath the eye. The juveniles have a bluish-black overall colour with thin white to blue coloured curved lines on their body. The dorsal fin has 13 spines and 20-21 soft rays while the anal fin contains 3 spines and 20 soft rays. This species attains a maximum total length of 45 cm (18 in).
