Country of Origin: Western Atlantic Ocean, including the Caribbean Sea, Florida Keys, and northern South America
Latin Name: Acanthurus coeruleus

Atlantic Blue Tangs are herbivores that feed primarily on marine algae. In captivity, their diet can be supplemented with dried seaweed, spirulina, and high-quality herbivore flakes or pellets. They are reef safe with caution, generally coexisting peacefully with corals but may show territorial behavior toward smaller or similarly shaped fish. Their bold coloration and active grazing make them a striking and beneficial addition to reef aquariums.
