Hello, I got a Argentine black and white tegu on Saturday Jan 8th and it has not eaten. It is about 4-6 months old. It has drank water at least once but all it seems to do is burrow under a hide in the cold side of the tank. Temp is around 100f on basking, 80-90 on hot side and 70-80 on cool side. At night it probably gets to around 65-75 with the lights off. Is this just normal brumation behavior?
