The Blackspot Angelfish is found in tropical marine waters feeding of plankton that is picked from the currents a few metres of the surface bottom.
Male Blackspot Angelfish are bluish white with narrow black bars on the body. The dorsal, anal and caudal fins have yellow spots. The caudal fin is lunate.
Female Blackspot Angelfish are yellow on top and blue below. The lunate caudal fin is bluish with a black stripe on the upper and lower edges.

The species occurs in tropical marine waters of the Western Pacific, from Malaysia, north to Japan, south to Australia and east to Fiji.
