Masked Swallowtail Angelfish

Masked Swallowtail Angelfish Female

Masked Swallowtail Angelfish is also known as the Japanese Angelfish and reside in the northwest Pacific Ocean from southern Japan to the Philippines. They inhabit rocky reefs and are often seen in small groups or harems consisting of one male and several females. Masked Swallowtail Angelfish, like others of the genus (Genicanthus) exhibit dramatic sexual dimorphism where females differ in coloration from males. Females have a cream to white color chest, which gradually changes to yellow along the top of the dorsal, with a dramatic black band over the eye and at the base and along the caudal fin. Males have a bright yellow-orange face that continues horizontally down the side of the fish, with narrow black vertical bars running the length of the fish to the caudal peduncle.
