Most will tell you that a clown tang should be avoided. They have a tendency to get really, really mean after settling in to a tank. If you are going to try to Acanthurus tangs, its best that you add them together at the same time, and make them the last fish added to the tank. Both the Sohal and the Clown are known for killing anything added to a tank after they have acclimated and settled in. You'd also want to keep them with other aggressive fish, which takes a lot of the normal 'reef safe' fish off the potential stocking list
