The Regal angelfish or the Royal angelfish (Pygoplites diacanthus). Their body is moderately elongate and is very compressed. The preorbital bone convex and has no strong spines. There is 1 prominent spine at an angle at the preopercal. The ventral edge of the interopercle is smooth. The eyes are moderately small along with the mouth that is terminal. The mouth is also protractile. They have a maximum length of 25.0 cm.  They have a total of 14 dorsal spines, and 17-19 soft dorsal rays. They have 3 anal spines and 17-19 anal soft rays. They also have 16-17 pectoral fin rays. Their caudal fin is rounded. The precise coloration of this fish can vary as regional differences can occur, most notably in populations from the Indian Ocean, Red Sea, and South Pacific Ocean. A commonality, however, is a body edged in narrow blue-white and orange stripes that are narrow and angle backward. They have been reported of living 15 years.
