Rock Beauty Angelfish's body is dominated by black, especially on its back. Bright yellow is the head, front and rear half of the body as well as the caudal fin. The eye has striking sapphire-blue accents. Similar in appearance, the juvenile's initial body is predominately yellow with a large caudal dark spot that seems to enlarge, overpowering the yellow coloration.
Great algae eater. Because of its need for sponges, the Rock Beauty Angelfish can be difficult to keep in a home aquarium. You should provide the marine angelfish a balanced diet that includes vegetables such as Spirulina and marine algae, as well as finely chopped meaty items and angelfish dishes containing sponges.
