A 180 gallon or larger aquarium is necessary to provide plenty of swimming room. It is aggressive towards its own species and conspecifics at times, but peaceful towards other fish in the tank. Introduce like species at once.
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 use a veggie clip, and feed at least 3 times per week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.
