I just got a new Argentine black and white tegu like a week ago he is about 5 months old. The first day I got him he took food no problem. But the second day he just stayed buried under his substrate and would not come out. So I waited a day. But he did the same exact thing the next day at first I thought he got out but then I saw the dirt move. The next day he came out to bask and when he was done I offered him so food but he would not take all of it only a little then the next day I tryed to give him food but he just stayed buried under his substrate and will not come out for nothing what should i do how do I getunder him out without stressing him out because I did just get him?
