Surgeonfish
Acanthurus coeruleus (also known as the Atlantic blue tang surgeonfish or the Atlantic blue tang) is a surgeonfish found commonly in the Atlantic Ocean.
Although the body of the reef fish can vary in shade from light to dark blue, the dorsal, anal and caudal fins are golden blue. As juveniles, the edges on their dorsal and anal fins and the rings around their eyes are purple-blue, blue or blue-green. Juveniles may also be larger than adults and are called Atlantic yellow tang surgeonfish until they become adults.[citation needed] Their colors change during growth from a yellow juvenile, yellow tailed blue subadult and the blue adult phase.
Acanthurus coeruleus is common off of Florida, the Bahamas, and other places in the Caribbean sea, including Bonaire. Blue Tangs are very common in Belize and especially Ambergris Caye. They are also common in the Gulf of Mexico. They are also found south to Brazil and north to New York and eat krill.
The fish is not under human threat. The Atlantic Blue Tang is caught for commercial fishing, but maintains little importance to Caribbean industry. It is also used, though rarely, as bait.
