A 125 gallon or larger aquarium is necessary to provide plenty of swimming room. It is extremely aggressive towards other Tangs or Surgeonfish, especially those similar in form and color, and should be the only one in the tank except in very large systems: introduce all at once if more than one is to be maintained in the same aquarium.

Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or veggie clip.
