The Flame Dwarf Angelfish is one of the most recognizable small angelfish in the hobby, wearing a fiery red-orange body crossed by several black bars, with dorsal and anal fins washed in purplish-blue. Coloration shifts noticeably by collection locality: fish from the Marshall Islands, Christmas Island, Hawaii, Cebu, and Tahiti differ in the amount of orange or yellow tint and in bar pattern and thickness. Adults reach roughly 4 inches, with males typically a bit larger and more intensely colored than females. The species is a protogynous hermaphrodite, so a dominant female can transition to male when no male is present.

Native to the tropical Central and Western Pacific, Centropyge loriculus occupies clear lagoons, seaward reefs, coral-rubble zones, and rocky crevices, generally between about 10 and 60 feet, with records extending considerably deeper. Replicating that structure matters in captivity. Provide a minimum of 55 gallons of mature, stable aquarium volume with generous live rock arranged into grazing surfaces, caves, and passageways; longer footprints are preferable because this angel patrols horizontally along rockwork rather than cruising open water. A secure lid is sensible, as marine fish of this type are prone to jumping.

Stability is the defining requirement of this species at the Moderate care level. Flame Angels do not tolerate significant parameter swings, and they are notably sensitive to copper, which should be kept below approximately 0.15 ppm during any treatment. Establishing the fish in a well-cycled system with an existing film of algae on the rock gives it an immediate grazing resource and eases the transition to captivity.
