Emperor angelfish

A type of marine angelfish is the emperor angelfish. It is a fish that lives near reefs and is found in the Red Sea, the Indian and Pacific Oceans, Hawaii, and the Austral Islands. This species typically has steady numbers and is not endangered in any significant ways. Because of its distinctive, vivid pattern of colors, it is a favorite among photographers, artists, and aquarists.

The emperor angelfish exhibits a clear distinction between its juvenile and adult forms. The bodies of the juveniles are dark blue with concentric curving lines that alternate between pale blue and white, the smallest of which are placed posteriorly and are totally encased within one another. At the front, these lines are vertical. The caudal fin is transparent, while the border of the dorsal fin is white.

The adults have a light blue face with a dark blue mask covering their eyes, horizontal blue and yellow stripes, and a yellow caudal fin. Above the pectoral fins, there is a blackish band, the top of which is above the level of the upper orbit. This band's front and back margins are both a vivid blue and a narrow yellow line, respectively. The anal fin bears a horizontal pattern of lighter blue stripes on a dark blue background.
