The **Rock Beauty Angelfish** is a captivating marine species, showcasing vibrant yellow and blue hues, native to the Atlantic Ocean. While they can be challenging to maintain in a home aquarium, once acclimated, they bring a remarkable burst of color to any aquatic setup.

As a smaller angelfish, the **Rock Beauty Angelfish** reaches a maximum size of about 9 inches. This size allows them to thrive in tanks as small as 125 gallons. It's advisable to avoid housing them with other angelfish unless you have a significantly large aquarium, as they can exhibit territorial and aggressive behavior towards similar species. Additionally, they may not be ideal for reef tanks due to their tendency to nip at corals and certain invertebrates like clams.

Juvenile **Rock Beauty Angelfish** are predominantly yellow, but as they mature, a blue spot expands to cover most of their body. Adult fish display a striking contrast with a yellow head and a deep blue body, complemented by sapphire blue eyes.

Maintaining a **Rock Beauty Angelfish** in a reef aquarium can be challenging, as they require a diet rich in sponges for optimal health. Supplementing their diet with algae, mysis shrimp, and Spirulina can promote growth and vitality. Providing ample live rock will offer algae for grazing and hiding spots.
