Apparently size does matter. I went and bought some large crickets, put one in and Skippy immediately jumped up and chased it down. Chomp...dinner was done. But Lucky, the one I'm worried about still wont come out and is completely buried. He wasn't in his water dish today because its still clean. So he hasn't come out at all. He did eat a wax worm last night so I wont bother him tonight but should I dig him up tomorrow night and try a cricket or just leave him be? It couldn't have gotten that cold in the office while I was gone. Low to mid 70's at the lowest. And both tanks were side by side with the exact same setup and Skippy's fine. If he was chilled he's been toasty at 80-82 degrees since I got back since last Thursday and I feel his soil everyday and its moist. Should I be worried or is this just a way pacmans torture us?
