The Mustard Tang, Acanthurus guttatus, also known as the Mustard Guttatus Tang, the White spotted Surgeonfish, has a black body with a white face and white vertical bands along with many white dots scattered across its rear, with a black tail and yellow pelvic fins. The general body shape of the Mustard Tang resembles that of a Sailfin Tang. Mustard Tangs are best kept in large reef tanks, away from members of its own species, or other tangs. There should be ample amounts of rock work for the Mustard Tang to hide, plenty of free space for it to swim, and enough areas for it to graze on algae. The Mustard Tang will eat an omnivorous diet but should be explicitly fed marine algae or seaweeds to keep its temperament and stress levels down. Overall, the Mustard Tang is a stunning surgeonfish that is compatible with most large reef tanks.
