of course, you can add the least aggresive of many different types together, like you can add a tang and some clowns and a blenny, etc etc. fish are usually more aggressive to ones of similar color and especially body type. so agressive tangs wont usually target clowns or gobies and vice versa, of course there is always an exception like a damsel. dont get damsels.
