Overview
The Rock Beauty Angelfish has a body that is predominately black, especially on the back half as an adult. The head and front half portion of the body, and the caudal fin, are a bright yellow. The eyes have striking sapphire-blue accents. Similar in appearance, the juvenile initially has a predominately yellow body with a large caudal black spot that just seems to enlarge, overwhelming the yellow coloration with the exception of the head, body area just behind the head, and the caudal fin.

The Rock Beauty Angelfish is difficult to sustain in a home aquarium because of its dietary requirement of sponges. The diet in the aquarium should include vegetable matter such as marine algae and Spirulina, finely chopped meaty items, and high-quality angelfish preparations containing sponges.
