Centropyge aurantonotus reaches 8 cm. Small dwarf angelfish with a deep purple-blue body and a characteristic vivid flame-orange back covering the dorsal fin. Cryptic in crevices and caves of deep Caribbean and Brazilian coral drop-offs between 15 and 150 m. Rarely seen by recreational divers due to its preferred depth. Valued in the aquarium trade, its deep capture makes the species locally vulnerable.
