Pomacanthus is one of many genera belonging to the family of marine angelfish (Pomacanthidae). He currently has about thirteen species. Seven species of Pomacanthus belonged to the genera Holacanthus and Chaetodon; P. annularis and pomacanthus Emperor (P. imperator) still meet under both former names — and Holacanthus, and Chaetodon.
In comparison with other fish the same size pomacanthus characterized by the elegant combination of beauty and grace. P. annularis is a beautiful example of a complex combination of spectacular colors, typical of pomacanthus. Copper-orange body is intersected almost diagonally glowing blue stripes, in the temporal region on each side by a blue ring. The caudal fin is white with copper-orange border, stretches back dorsal, pectoral and pelvic fins are a bright copper-orange on the ventral blue band. This is a classic of the sea a handsome man, and yet he lacks the personality to take a leading role in its kind, since many pomacanthus look just as good.
For juveniles of all pomacanthus typical banded pattern. The grey (P. arcuatus) and minor (R. paru) angelfish black body decorated with yellow hoops, pelvic and anal fins —small blue label. Teens P. zonipectus have similar coloring; in addition, these fishes the body is covered with beautiful blue stripes. To distinguish between gray and small fry of angels quite difficult. The most reliable distinguishing feature are marks on the tail: small angel caudal fin has a yellow rim, gray — yellow stripe in the shape of a Crescent. Other species of the genus are characterised by a complex pattern of blue and white stripes on a black body, this species-specific trait.
Arab and emerald angels retain the yellow coloration of the caudal fin throughout life — from larvae to adult fish. Yellow tail emerald angel in the middle is crossed by a light blue pattern. Fry Arab angel has an extra mark-the curved yellow stripe running from the rear of the dorsal fin to the point of dividing the body in half. When ripe pomaranczowy delicate colors teenagers gradually replaced by adult coloration, many species even more beautiful. Pomacanthus are most often found in oceans at a depth from 3 to 26 m, the shallow water limit is 0.6 m or less. Some angels, such as Emperor, sometimes found at depths greater than 60 m.
The distribution of certain species is very limited. The estimated borders of the area are Arabic angel and angel Cortez indicate that they are endemic to very small areas: the first is in the Red sea, the second — in the Eastern Pacific ocean. However, this slight expansion of atypical for the genus Pomacanthus. Many species of pomacanthus ubiquitous in quiet areas and (or) Indian oceans. Various pomacanthus. including Imperial and semicircular angels, found in New Guinea, Malaysia, Indonesia, East Africa, the Great Barrier Reef, Western Australia, Solomon Islands, New Caledonia, the Philippines and Seychelles and the Red sea. It is possible that the species range of which is limited, will ever be able to be found in other habitats.
Grey and small angels live in the tropical waters of the Atlantic ocean, and gray angels are sometimes found even in the far North, in New England. Adult individuals of these species is much less colorful than pomacanthus from the Pacific and Indian oceans, in addition, they sometimes need a lower temperature.
