My Powder Blue Tang has recently turned into a giant turd. He's been picking on the Copperband Butterfly which is about his size and barely lets the other fish eat. He also dinged the Butterfly. I have been trying to catch him. I made a fish trap and he doesn't want much to do with that. I tried to catch him with a hook after I filed the barb off. Tried wax worms and some squid. Won't go for that either. Tonight I see my 15 year old clowns have also taken a couple hits. The male isn't looking well at all. Anyone have any brilliant ideas for catching this fish or will I be tearing down my reef to snag my problem fish?
