Peal-Scaled Angelfish are found in tropical marine waters of the Indo-West Pacific, from Christmas Island, throughout South-east Asia and Micronesia, north to Japan, south to Australia and east to the Marshall Islands. Pearl-Scaled Angelfish are most commonly found on rocky or rubble bottoms of offshore reef slopes and lagoons, especially those with rich algal and sponge fauna.
In the aquarium environment they require strong reef/rock work with many caves and crevices to provide this species with a place to hide when threatened; as well as, area to graze for marine algaes.
The Pearl-scaled Angelfish is brown to grey-green throughout the front and middle of the body and black around the tail section. The anal fin, caudal fin and posterior region of the dorsal fin have blue margins. The iris, pectoral fin base and area around the eyes are orange.
