Ok so I have a powder blue tang in my tank that is causing nothing but problems. I have done everything in my power to catch him. I have tried meting him myself and even had a few people who work in aquarium store come over an try. I tried the 2 liter bottle trap and he never goes near it. I can't pull the rock out cause it's all glued together and tons of coral on it. I'm at my last nerve. He's going after fish all the time and forget trying to add anything new. I even tried a cleaner wrasse and he killed it minutes after I dropped it in there. I feel like the only thing I could do it put something in there to keep him in check. I just donno. Maybe another powder blue? I forgot to say the tank it 250g and there are several tangs including a blue hippo, yellow, virmini, bristle tooth and a few other ransoms. What is anyone's thoughts on this
