The Blue Tang relishes a good hiding location amongst live rock. However, this active fish also loves to swim. Therefore, ample room to roam around your aquarium is essential for optimum health. Though peaceful towards most tank mates, the Blue Tang will become aggressive towards other fish of its own species. To keep multiple specimens, introduce the entire lot 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 the Blue Tang's 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 three times per week. Ensure highest water quality and a varied diet, rich in nutritious marine-base vegetables to keep your Blue Tang in optimal health
