How big is his enclosure? You said you gave him a bigger hide. They like small spaces. Give him a small hide that has only one entrance, the hide should be a little cramped. Also his enclosure may be to big. What size is it? Can you include a picture of your setup. What I'am getting at is he may feel threatened by being in such a big space. That's why you see him being so agressive. So please post the pictures of his home etc. I'm sure we can calm him down with a few adjustments.
