Acanthurus xanthopterus

Acanthurus xanthopterus, commonly known as the yellowfin surgeonfish, is one of the largest tangs so it needs a large tank to grow to the beutiful fish it can become. It can be aggressive towards other tangs and food competitors, but will generally leave other fish a lone. A great algae eater for a very large sized tank.

Like other tangs, it will eat meaty foods, but it's important it can graze on algae/seaweed the entire day to ensure it will stay healthy. So feed flakes/pellets multiple times a day and make sure there is always seaweed available.
