Raising the light will certainly help the temp. Have soaked him? If not you might give that a try. I soak mine at least a couple of times a week. It might wake him up a bit. It's also the time of year that their little internal body clocks tell them it's time to hibernate so the could possibly have something to do with it. Maybe not though since its been so warm in his enclosure. Hmmmm. I'm just throwing ideas out there. A soaking will do him good one way or the other. Use a shallow pan with lukewarm water about the depth of where his top and bottom shells meet. You may already know that. Offer him food after the soak. Good luck. One of my Russians is a new rescue and she is also staying buried all the time. I've only had her for a week though and I think she wants to hibernate. My other Russian is very active so I'm hoping my new one "Honey" will come around. Let us know what happens. Oh and welcome to the forum
I agree, my russian slows down during the 'winter' time and though I don't hibernate, he usually stays buried and sleeps through most days in the winter during 'brumation'. He will also need a few weeks to settle in, and get used to his environments
