The family Pomacanthidae, commonly known as angelfish, consists of colorful marine fish found primarily in tropical and subtropical oceans. They are characterized by their laterally compressed bodies, vibrant colors, and distinctive patterns. Angelfish inhabit coral reefs and rocky areas, where they play a vital role in the ecosystem by grazing on algae. There are about 86 species of angelfish, which are divided into two subfamilies: Pomacanthinae and Centropyge. The latter includes the smaller dwarf angelfish, while the former comprises larger species. Angelfish are popular in the aquarium trade due to their striking appearance and unique behaviors, making them a favorite among marine enthusiasts.
