Hi everyone, Im new to the community and just got my first tegu. I purchased him from underground reptiles and they said he was a black flame tegu, 50% Chacoan and 50% argentine red, he is about 8 inches. I have him in a 36, 18,16 enclosure with about 5 to 6 inches of eco earth. i have a 100 watt basking line and an 18 inch uvb light. My issue is that within a day of putting him in his enclosure he has gone into his hide and dug underground. I understand that tegu's hibernate but i am concerned that I havent really had him for long and do not know much about how how this works. I woke him up and have tried feeding him and he refused 3 days in a row and on the fourth he ate a pinky. He will not come up unless i wake him. Is this normal and for how long will this last? Also, should I upgrade to a powersun 100 or 160 watt?
