It was winter time last year both of them dug in, can't say specifically. They haven't come out to eat or anything, tho they're still same size or even larger. Fat round and the same color. I think one of them took a couple of crickets at one point, like three. No where near the amount usually eaten. I just checked and he was at the bottom. he positioned himself under the lamp so maybe he was getting hot. I flipped the light to the opposite side and we'll see if that works. What am I looking at as far as them not coming out? I know for certain it's been more than 6 months. I'd still say at least 8.
