I've had my little guy for a few weeks now and everything's been great! He's eating and digging and I even caught him hanging out in the water dish. This morning I get up and he's nowhere to be found! He usually hides under one of the rocks or pieces of wood, but he also made a 4-5 inch deep burrow. When I found he wasn't under anything, I checked in his burrow (which was right along the glass). It was all caved in! Do you think he buried himself? He's either buried in there, or aliens abducted him. He's young, about 2 inches long, so should I be worried? Or will he crawl out of his hole in good time? ANyone ever seen this before?
