I only have one fish in my tank which is a true percula clown he has been in my tank for around 3 months he used to stay in the one side but roams the tank all the time , I just noticed lately if I move corals or even stick my hand in the tank he attacks me like crazy doesn't matter where my hand is in the tank . My question I have been stocking up on pods for months to get a mandrin or another fish do you think he will attack any fish I put in the tank since I'm assuming he must think he runs the tank now since he is the only fish.
