As long as he ate that's good. Just leave him be. He will find the warm spot to digest, or he will just crawl around till he is ready to settle. Long as the hot and cool sides are good don't worry about it. As far as his escape.....shut, lock, double and triple check all tanks before leaving room!!!! Did I say double and triple check the tanks and locks.....Your lucky you saw him or he might of been gone forever! CHECK CHECK CHECK the locks!!
