Atlantic Blue Tang – Acanthurus coeruleus – Medium Adult

The Atlantic Blue Tang (Acanthurus coeruleus) has a rounder body than most other oval-shaped Acanthurus tangs. As juveniles, they are yellow in color and become more violet-blue as they mature, although their social structure means that very small fish may have adult coloration while larger fish may still be juvenile. The tail is the last part of the fish to change. Both juvenile and adult fish have a yellow scalpel spine at the base of the tail. They are found mostly along the western Atlantic coast as well as the Ascension Islands closer to the African coast.
