The **Annularis Angelfish** is a prominent species inhabiting the Indo-Pacific waters. This angelfish is an excellent choice for large, fish-only aquariums.

Reaching up to 12 inches, the **Annularis Angelfish** requires a minimum tank size of 220 gallons. Juveniles are black with blue stripes, which evolve into electric blue lines on a golden brown body as they mature.

While not ideal for reef tanks, the **Annularis Angelfish** may occasionally nip at corals and invertebrates like clams. Their compatibility with reef environments depends on individual temperament. They can be aggressive towards similar species, so it's advisable to keep only one in smaller tanks.

As omnivores, **Annularis Angelfish** thrive on a diet of meaty and plant-based foods, including mysis shrimp, brine shrimp, spirulina, pellets, and high-quality flakes.
