About Three-Spot Angelfish

A small, disc-shaped angelfish with a predominantly yellow body and three distinctive dark blue-black spots: one on the head, one on the upper body, and one on the rear dorsal region. The fish has a rounded profile typical of pomacanthids, with pointed dorsal and anal fins. Adult coloration is bright and contrasts sharply with the dark markings.
