Any of various fishes of the order Perciformes.The best-known angelfishes are freshwater cichlids (genus Pterophyllum) popular in home aquariums. These are thin and deep-bodied fishes that usually are silver with vertical dark markings but may be solid or partially black; they may grow to 6 in. (15 cm) in length. Brightly coloured marine angelfishes are in the family Pomacanthidae. They are found among tropical reefs in the Atlantic and the Indo-Pacific, where they eat algae and marine invertebrates and reach a maximum length of 18 in. (46 cm).An aquarium angelfish (Pterophyllum)Jane BurtonBruce Coleman Ltd.* * *
▪ perciform fishany of various unrelated fishes of the order Perciformes. The angelfishes, or scalares, popular in home aquariums are members of the genus Pterophyllum and the cichlid (q.v.) family. They are thin, deep-bodied fishes with elongated dorsal, anal, and pelvic fins. Depending on the authority, one to three species may be recognized: P. scalare (scalare), P. eimekei, and P. altum. Angelfishes are native to the freshwaters of tropical South America and may grow to a length of about 15 cm (6 inches). They are commonly silvery with vertical dark markings but may be solid or partially black. They are carnivorous and take care of their eggs and young.The brightly coloured marine angelfishes seen among tropical reefs are members of the family Pomacanthidae. Sometimes placed with the similar butterfly fishes in the family Chaetodontidae, they are compressed, deep-bodied fishes with small mouths and rather rough scales; the largest grows about 46 cm (18 inches) long. These angelfishes are distinguished from the butterfly fishes by a sharp spine on each cheek. These angelfishes feed on algae and various marine invertebrates. The family, which includes fewer than 100 species, is represented in both the Atlantic and the Indo-Pacific. In many species, colouring of the young differs greatly from that of adults.Among the better-known species are the black and gold angelfish (Centropyge bicolor) of the Indo-Pacific; the French angelfish, Pomacanthus paru (or P. arcuatus), a black and yellow species of the Atlantic; and the queen angelfish (Holacanthus ciliaris), a blue and yellow fish of the Atlantic.* * *
