Hello, I recently purchased a blue tegu from underground reptiles and they claimed he was about 5 months old, and he's around 20 inches long. I'm keeping him in the proper setup etc. 110 degree basking spot, 75-80 ambient, hide boxes and substrate to bury in etc. I've had him for 5 days and I've offered him chicken hearts, gizzards. and ground turkey (all raw) and he's only taken a few small bites of turkey for me over the 5 days I've had him. All he seems to do is bury himself and stay there and doesn't seem to bask. The only time he ever sits under his basking spot is when I unbury him and take him out, and then place him back in his enclosure. He basks for about 30 mins and then buries himself again. Is this normal behavior or should I be worrying? And are there any foods I can try that may get his appetite going that tegus go crazy over? Thanks for any help.
