A 150 gallon or larger aquarium is necessary to provide plenty of swimming room. It is aggressive towards other Tangs and may be harassed by its own species, but is peaceful with other fish and sessile invertebrates. It is best to house only one specimen per tank.
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.
