The members of the family Pomacanthidae are generally know as angelfishes and, like their nearest cousins, the butterflyfishes, are regarded by many divers and aquarists as being amongst the most beautiful and majestic fishes in the sea. The majority of species occur on shallow reefs in coral, algae and sponge zones, most going little deeper than about 30m but where conditions are pristine and water is very clear, many species go much deeper and few species only live deep (over 100m). Angelfishes feature a large and distinctive backward-protruding spine from the lower corner of the gill-plate (cheek spine) from which the family name was derived. This cheek-spine is diagnostic for all the species , even at juvenile stage, and readily separates any angelfishes from butterflyfishes that may be similar in shape. Mot angelfishes are robust with compressed, ovate to rhomboid shaped bodies, covered with small or tiny scales, and have a continuous dorsal fin. The mouth is small and jaws are set with many small, usually tricuspid teeth that are used for grazing algae or scraping sponges and other sessile invertebrates. Few species combine their diet with a variety of foods and some are planktivores.

Place of origin:Western Indian Ocean
Indo-Pacific, ranging from East Africa and the Maldives to Samoa, South Pacific, north as far as Japan and south to New Caledonia, but Indian Ocean and Pacific forms are different. Found in clear lagoons and outer reefs at depths of 3-60m, but prefers manly deeper zones of the reef. This fish shines beautifully yellow, and has three name giving spots: a black one (often split in two in adults), on the forehead, and one on each side (almost the color of the body), 'ear-like', behind the head. Length to 25 cm.
