The trapezoid angelfish ( Pomacanthus rhomboides ) lives in the southern Red Sea and in the western Indian Ocean along the coast of East Africa to Knysna in the South African province of Western Cape as well as in the Seychelles and Madagascar . It seems to be particularly common in Maputo Bay in Mozambique . It prefers reefs close to the coast with depths of one to twenty meters.
The fish feed on sponges and bottom-dwelling invertebrates as well as plankton . In addition to the angelfish of the genicanthus genus , the trapezoid angelfish are the only members of their family that catch plankton in open water.
features
Trapeze angelfish have a typical trapezoid shape, dorsal and anal fins are not extended. The front body and the fins are dark gray-blue in color, the rear third of the body is a bit lighter, pale gray-blue, the belly and throat shimmer a bit reddish. The center of each scale is darker. Trapeze angelfish grow up to 46 centimeters long.
Fin formula : Dorsal XI – XIII / 22–25, Anale III / 21–23
The fry are similar to those of the ring angelfish and, like many angelfish juveniles , have a pattern of white and light blue horizontal stripes on a dark blue background. Their caudal fin is transparent.
