Neon Demoiselle

Pomacentrus coelestis, the Neon or Celestial Demoiselle, is one of the most vividly colored damselfishes available for marine aquariums, displaying an electric blue upper body that fades to a luminous yellow on the lower flanks and belly. Distributed from Cocos-Keeling to Samoa across the Indo-Pacific, it is significantly more peaceful than many Pomacentrus relatives and makes a lively, attractive addition to reef systems. Best introduced to a well-established aquarium with sufficient hiding spaces.

Provide a reef aquarium with abundant live rock for territory definition and hiding. Feed a varied diet of quality marine flake, frozen mysis, and enriched brine shrimp. Introduce singly or as a small group simultaneously to minimize inter-species aggression. Avoid adding to tanks with passive or timid fish.
