Emperor angelfish

Characteristics

Occurs singly. Juveniles of the Pomacanthus genus can be similar in appearance and may be easily misidentified. In Indonesia, the species was reported to clean an Ocean sunfish (Mola mola), by removing and ingesting its ectoparasites (parasites that live on the outside of the host’s body, such as on the skin, and not inside, such as in the gut). Spawns at dusk.
