Wikipedia

Pomacanthus navarchus

Blue-girdled angelfish, Pomacanthus navarchus is a marine angelfish from the Indo-Pacific ocean as well as some parts of the east Indian Ocean. It occasionally makes its way into the aquarium trade. The Majestic Angelfish is one of the smallest of the larger species of angelfish. It grows to a size of 41 centimetres (16 in) in length, but usually much smaller, and can live to be up to 21 years old. Younger fish stay closer to the shallows, but the more mature fish can be found up to 120 feet (37 m) deep. Majestic Angelfish eat mainly sponges and tunicates. Juvenile fish are mostly blue in color with white stripes. As they mature, they take on a yellow coloration on the flanks, dorsal fin, and tail as seen in the image at right.
