Blue Tang

Acanthurus coeruleus


The juvenile color phase of the blue tang is bright yellow with a blue eye ring and blue fin edges on the dorsal and anal fins. As the fish grows, the yellow transitions to a light blue-gray color, usually starting with darker bars on the body. In the subadult phase, the tail often remains yellow. Eventually, the entire body and tail transitions to the darker blue adult coloration with bright blue fin edging.


Reef near Stingray City.
