Appearance

Adult yellowband angelfish are violet-blue with a large yellow mark on the middle of its body. Scales on the forehead and above have dark edges. Dorsal and caudal fins have yellow patches with light blue markings. Males and females are similar in appearance.

Juveniles are dark blue with several white and light blue bars along the sides. Their caudal fin is transparent. Once they grow to about 6 cm the yellow markings begin to appear. Adult colors appear when these fish reach 10 to 15 cm.

Yellowband angelfish can grow up to 40 cm.

Habitat

Coral reefs, rocky areas and protected, silty bays with coral

Diet

Algae, sponges and invertebrates such as worms and molluscs

Life History

They live in groups with a haremic social system where one male defends a territory with 2-5 females. Yellowband angelfish have both male and female reproductive organs. The largest and socially dominant individuals become male to defend and control the harem. In the absence of a male, the largest female in the group will become male.

Reproduction occurs by releasing eggs and sperm into the water. Eggs are planktonic, meaning they float along ocean currents. After hatching, juveniles eventually settle onto reefs and develop into adults.

Maximum age is estimated to be 36 years.

IUCN Status

Least Concern
