HiWe have no way of knowing just by what you've written for us.
Are his eyes open? Closed and sunken in? Does he stink? Is his body stiff?
If your temperature in the enclosure is as it should be, he's not hibernating.
I'm sorry to say, he's probably dead. Even when brumating, a tortoise will move if you mess with him.
Depending on where you bought your tort can have a lot to do with the health when you purchased.Thank you for your reply im not sure now as to why hes died at such a young age but thank you again for your quick respose x
