Rock Beauty Angelfish

The Rock Beauty Angelfish, *Holacanthus tricolor*, is a stunning and iconic species from the Western Atlantic. Its vibrant coloration features a striking contrast of bright yellow on the head and tail, separated by a large, velvety black patch covering the body. This bold pattern makes it an eye-catching addition to any marine aquarium.

A minimum tank size of 75 gallons is recommended for a single Rock Beauty Angelfish, with larger tanks preferred for adults or if keeping with other fish. They are considered to have an intermediate care level, requiring stable water parameters and a varied diet. While generally peaceful, they can become territorial, especially towards other angelfish or similarly shaped fish. Providing ample live rock with plenty of hiding places is essential for their well-being.

In the aquarium, the Rock Beauty Angelfish will readily accept a varied diet of high-quality marine flake food, pellet food, frozen mysis shrimp, enriched brine shrimp, and marine algae. Offering a diverse diet is crucial for their health and to prevent them from nipping at corals or invertebrates, although they are generally considered less prone to this behavior than some other angelfish species. They typically reach a maximum size of around 10 inches in captivity.
