The yellowtail angelfish ( Pomacanthus chrysurus ) occurs in the western Indian Ocean from the Gulf of Aden to Natal (South Africa), near the Seychelles , Comoros and Madagascar .
The species is little known and hardly researched. It lives solitary or in pairs in coral-rich reefs at depths of one to 25 meters. The fish feed mainly on sponges and algae.
features
Yellow-tailed angelfish grow up to 33 centimeters long. Their basic color is dark brown, throat and neck are ocher. Six white horizontal stripes run across the body, which bend in the dorsal fin to the rear tip. The tail is lined with yellow and blue at the back. The eyes, gill cover and mouth are lined with blue lines. The anal fin and the pelvic fins also show a pattern of narrow blue longitudinal lines. Directly above the gill cover, at the beginning of the sideline, there is a black spot surrounded by an orange ring, which is why the fish is called “Ear-Spot-Angelfish” in English.
Fin formula : Dorsal XIII – XIV / 17–19, Anale III / 18–19.
Like many angelfish cubs, the juveniles wear a very different color dress. They are rather dark blue, also throat and neck, and show narrow light blue stripes between the white horizontal stripes. The ear mark above the gill cover is missing.
The yellowtail angelfish hybridizes with the sickle angelfish ( Pomacanthus maculosus ), which occurs in the same area of distribution.
