Hey ofa, does yours tailslap you? mine didn't before but he has become considerably more aggressive since he is alone now. I have been the victim of that many time recently. I have seen him tail slap and break my thermometer and crack my heater, he has completely tore up all my fake plants. Its funny cuz one day I'll see him run into a hard plant leaf, then the next day the exact same leaf will be floating, just clipped right off....
