About
Overview
The Yellow-ear Angelfish is a striking marine species native to the northwestern Indian Ocean, including the Red Sea, Gulf of Aden, and the Persian Gulf. It is typically found inhabiting coral-rich areas and rocky reefs, where it is often observed swimming in pairs or small groups.
Appearance
This species is characterized by a largely white to light-colored body contrasted by a dark, often black, head. It derives its common name from a distinctive yellow spot located on the upper preoperculum, near the gill cover. The dorsal and anal fins are primarily black with prominent white margins, while the tail is typically yellow. Juveniles display a different pattern, featuring a wide black band over the eye and an oblique black patch on the back that gradually fades as the fish matures.
Biology & behavior
Primarily non-migratory, this angelfish is known to be a shy species that becomes more active over time. It is generally encountered in coral-rich environments and on outer reef slopes. While it can be territorial toward other angelfish, it is often found in pairs or small groups in the wild.
Feeding
As an omnivore, the Yellow-ear Angelfish primarily grazes on benthic invertebrates, with a strong preference for sponges and tunicates. Its diet in the wild also includes various types of algae.
