So ive just gotten my 2 foot tegu in the mail yesterday morning. He was perfectly healthy and interactive. After he finished basking a few hours later, i sat beside the open cage playing on my phone. I Also have him some food since he seemed hungry (idk if it is correct to give him food this early). He ate it happily. I sat by the cage all day somewhat ignoring him. I turned off his light at night. This morning as i turn on the basking light, he was inside the hide (he covered the entrance with substrate). Yesterday, he was always out all day so im guessing he is brumating? Is it possible he brumated the day after he arrived? Also, i should mention i live in a tropical country, he came from the city beside mine so its not too far away or anything. Although, the city he came from is a bit hotter than mine 78-89f, mine is around 78-82f and can drop to 70 at night (outside) 73 inside. Im worried that this is too cold for him and made him think winter is coming since its colder than what he is used to?
