The adult is generally dark greyish-black with a broad, crescent-shaped sash of yellow and a yellow tail. The dorsal fin has 12 spines and 19–20 soft rays and is elongated into filaments which trail behind the fish as it swims. The anal fin is also extended by filaments and has 3 spines and 18 to 20 soft rays. The pectoral fins have 17 to 18 rays. The juveniles have an altogether different appearance. They have a base colour of steely blue with a number of vertical, meandering stripes of white and pale blue.[3] Distribution and habitatThe Arabian angelfish is found along the eastern coasts of Africa at depths up to {{convert|15|m}}. Its range extends from the Red Sea and the Gulf of Aden to Zanzibar. It can be found also in the Persian Gulf. There are unconfirmed sightings of this species off the coast of Florida.[3] Its habitat includes sheltered coastal reefs with hard and soft corals, rocky reefs, crevices and the mouths of caves. It is timid which makes it difficult to observe.[3] BiologyThe Arabian angelfish feeds predominately on tunicates and sponges. The eggs are laid singly on the seabed.
