Common name: Narc angelfish

General information

The Narcosis Angelfish, Centropyge narcosis, is a rare and highly sought-after species in the marine aquarium trade. This dwarf angelfish is known for its striking coloration, featuring a deep blue body with vibrant orange to yellow accents on the edges of its fins and tail. The Narcosis Angelfish is a member of the family Pomacanthidae and is endemic to the deep reef slopes of the Pacific Ocean, particularly around the Cook Islands and Tahiti.

Due to its rarity and the depths at which it is found, the Narcosis Angelfish is not commonly available and commands a high price when it does appear in the trade. Its name 'narcosis' refers to the condition known as nitrogen narcosis, which divers can experience at the depths where this fish is typically collected.

Care

The Narcosis Angelfish requires a well-established aquarium with plenty of live rock for grazing and hiding. It is a relatively peaceful species but can show territorial behavior, especially towards conspecifics or similar-looking fish. A varied diet of marine-based foods, including algae, mysis shrimp, and high-quality angelfish preparations, is essential for maintaining its health and coloration.

Reproduction

Like many marine angelfish, the Narcosis Angelfish is a protogynous hermaphrodite, meaning individuals start life as females and can change to males if the social structure within their group requires it. Breeding in captivity is rare and challenging due to the specific environmental conditions needed for spawning and larval development.

Habitat

The Narcosis Angelfish is found on deep reef slopes and drop-offs, typically at depths ranging from 50 to 150 meters (165 to 492 feet). It prefers areas with abundant coral growth and crevices for shelter. Due to the depths at which it resides, it is less impacted by human activities but can be affected by changes in deep reef ecosystems.
