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:Coral Sea
Tropical Australian waters, ranging to southern New Guinea and nearby islands of Indonesia. Occurs on coral rich substrates, usually found shallower than 20 metres, but also known from trawled specimens from continental shelf. Adults are dark blue with a very broad vertical yellow band behind the eye (has white area behind eye, especially in males) from below dorsal origin to abdomen, joined by a distinct curving yellow band on black continuing onto caudal peduncle. Mouth and caudal fin yellow. Males busily marked with fine blue stripes, while females are plain dusky or covered with fine blue speckles. Juveniles similar to adults. Adults occur in small loose groups. Length to about 26cm, rarely larger.
