Species group: Marine Angelfish
Other common names: Annularis Angelfish; Blue-Ringed Angelfish
Scientific name: Pomacanthus annularis
The Blue Ring Angelfish has an overall brownish yellow body with blue stripes. Two of the stripes run across the fish's face, one through the eye and one under it. The Annularis also has a spotted look from the minute dots on its disc-like body. The caudal fin is white to light blue. A spot found behind the eye is brownish surrounded by blue. Both the dorsal and anal fins are brown, gradually changing to dark blue towards the posterior.
These fish are considered to be semi-aggressive. They are not reef-compatible and are observed to nip at sessile invertebrates. This fish is territorial, and usually found as solitary individuals in the wild.
A single Annularis would require a tank capacity of 70 gallons equipped with enough hiding spaces to ensure that the fish can seek refuge. Rock plants mimic the natural surroundings that it is used to in the wild.
