Annularis Angelfish is also referred to as the Blue Ring Angelfish and Blue King Angelfish because of its stunning sapphire stripes on an overwhelmingly brown body and the whitish-blue tail. A minimum of 200-gallon tank size is needed for an Annularis single. Make sure you have plenty of hiding spots like caves or live rock to feed. One word of caution This species can nibble at sessile invertebrates right from the bottom like corals, nudibranchs as well as tridacnid (three-footed) clams. Therefore, this Annularis Angelfish would not make an ideal reef dweller. The Annularis is considered to be semi-aggressive. Annularis could become territorial after having adjusted to its tank. The majority of Angelfish are considered to be hermaphrodite, and, as such, it's difficult to distinguish between males and females. An Annularis' diet Angelfish must include meats, vegetables and angelfish food preparations with sponge-like products. At first, the fish might need to be fed live food like brine shrimp or freshly cut seafood to encourage it to eat.
