The Rock Beauty Angelfish (Holacanthus tricolor) is also known as the Rocky Beasty, Corn Sugar, Coshubba, and the Yellow Nanny. The Rock Beauty Angelfish as an adult has a body, that is mainly black especially on the rear section. While the head, front half portion of the body, and the caudal fin are a bright iridescent yellow. The eyes have striking electric-blue accents. The juvenile initially has a predominately yellow body with a large black spot that just seems to enlarge as they mature.
The Rock Beauty Angelfish is a shy creature that requires lots of hiding places in a rocky Aqua-scaped aquarium with ample amounts of live rock for grazing on microalgae and diatoms.
While they sometimes can harm non-sessile invertebrates such as shrimp or crabs.
They may also occasionally nip at SPS corals and some species of polyp corals or zoanthids. Although if they are well fed on a diet of Spirulina, marine algae, high-quality angelfish preparations, mysis or large chunks of raw meaty frozen shrimp, squid, clam, and mussels they should tend not to bother corals as much.
Saltwater Angelfish are from the Pomacanthidae family. They are found along shallow reefs in the tropical water of the Atlantic, Indian and mostly Western Pacific Oceans. The Pomacanthidae family has approximately 86 species.
Saltwater Angelfish are incredibly colorful and come in a variety of sizes. With their bright colors and deep, laterally compressed bodies, the Angelfish are some of the more colorfully visible residents along any reef. For the most part, Saltwater Angelfish prefer to live among shallow reefs. They like moving about and feeding during the daytime, and at night seeking refuge among crevices and small caves in the reef and rocky outcrops.
As juveniles, some species of Angelfish will have a completely different coloration and markings than they do as adults.
As Adults, the Angelfish becomes quite territorial towards other adult Angelfish, especially from the same species.
Many are solitary, but some are found in pairs, or living in small groups consisting of a singular dominant male and several females. Most people don’t know the Angelfish is protogynous hermaphrodites, which means as juveniles they start life as a female and as they mature the dominant specimens in each group turn into a male. The males can also revert back to female if the social status changes at any time.
Many species of Saltwater Angelfish have streamer-like extensions of the soft dorsal and anal fins. All the Angelfish have small mouths, relatively large pectoral fins, and rounded tail fins.
Saltwater Angels are among one of the most popular fish for the home saltwater aquarium, and most Angelfish adapt well to captivity. The Angelfish nutritional needs consist of microalgae, macroalgae, sponges, and zooplankton. It is advisable not to keep Angels from the same genus in the same aquarium, as territorial fighting will usually occur.
should include Spirulina, marine algae, mysis shrimp along with other meaty fare, and live rock for grazing.
