Rock Beauty Angelfish (Holacanthus tricolor) Care
The Rock Beauty Angelfish, Holacanthus tricolor, comes from the Western Atlantic Ocean, from the state of Georgia in the US down to Brazil. It has a yellow body with a blue/black spot the start small as a juvenile and expands to cover much of the body as an adult. The head, front half portion of the body, and the caudal fin are a bright yellow. The eyes are accented with a bright blue.
The Rock Beauty Angelfish are omnivores that require a diet of marine algae, angelfish food, and a variety of meaty foods. They do best in an aquarium that is at least 125 gallons or more and has plenty of live rock to graze on and hide in. They do not do well with other angelfish or fish that are similar in size or appearance to themselves.
They are considered reef safe with caution because they have been known to nip at clam mantles and corals.
