Sorry about the slow reply,been busy.
I have moved him into the snake room(on wednesday night) so he has lots of peace and quiet.
Would it be worth handling him a little bit each day? then he may work out i am the meal ticket not the bad guy.
His temps are good,lot's of hiding places,sand substrate,small water bowl,darkness at night time.
I can't realy think of anything else i can do for him?except for leave him and wait.
