My male has went off for months at a time. They wouldn't eat f/t anymore and I offered a small rat (way under what he can eat) and BAM! Been on live ever since, he only wants to eat a couple times a month and sometimes he goes off but I would try live and see if it jump starts him. If he does then maybe try sticking with live or transition back to f/t. As long as they don't lose any weight I'll typically wait them out and keep offering. Good luck!
