The Ring Tail Tang (Acanthurus auranticavus) is commonly referred to as the Ring Tailed Surgeonfish. The body of this fish is a dark brown to black color with blue edging along the dorsal and ventral fins. They have a white ring around their tail fin which is how they got their name Ring tailed Tang. It is one of the easiest surgeonfish that can be cared for by intermediate fish keepers. If you want to keep more than one in the same tank it is advised to get juvenile specimens and introduce all of them to the tank at the same time. This Tang should be housed in a tank with plenty of hiding places and plenty of free space for swimming. It is very sensitive towards rapid changes in the water parameters. They are herbivores and should be fed a diet containing algae, veggie foods, and some meaty foods. It prefers to graze upon the rocks that are covered with algae so an established tank is recommended.
