I have had my purple tang in QT for about 4-5 weeks. I think it is time to add him to the tank. I know that purple tangs are notorious for being aggressive, but is that towards all fish or only larger fish? I am thinking that I may want to add a wrasse or blenny in the future - will he attack them? Should I get everything I want and make him the absolute last addition? Any advice/suggestions would be appreciated. Thanks in advance!
