Centropyge narcosis is referred to as the Narc angelfish and a spectacular rarity from the Rarotonga and Cook Islands. The Narc angel has a brownish-yellow body with yellow fins; a prominent black spot just dorsal to centre of body (not to be confused with juvenile C. flavissimus, which may have a prominent blue-margined black ocellate spot at centre of body). He is observed within interstices of cracks and caves along vertical drop-offs at depths below 100 m (328 ft.). The Natural diet is unknown but it accepts a wide range of food. Centropyge narcosis forms pairs or small groups in the wild. The Narc angelfish is almost never exported through the aquarium trade in Europe or the USA, Canada or even Japan. Not much else is known about this species.
