Other than not eating he acts fine. Spends 90% time hiding. Sometimes he comes out at night for a bit. Moves from warm side to cool side of the tank off and on. Seems pretty normal to me.
I really wouldn't mind feeding live. Heck I think it would be easier and I wouldn't have to listen to my wife complain when she finds a rat thawing in the kitchen sink. I just don't know what to do with the stupid thing if he refuses it.
