Ornate Angelfish Genicanthus bellus

The Ornate Angelfish, also called the Bellus Lyretail Angelfish, is native to rocks and reefs of the western Pacific and eastern Indian Oceans. Adults reach 18cm long. The more colourful female, with bright blue and black markings, is shown above.

The male has a yellow-gold lateral and dorsal line on grey-white (the one above is particularly dark). Living in groups, all juveniles are female. Adults have a hierarchy in order of size with the largest transitioning to become the male of the harem when the current male dies or is removed.
