He eats like crazy, so I'm not worried about that. And I don't know how old he is because I got him from a pet store (probably not the best idea) and they didn't know. Plus I haven't been able to measure him because I can't find a tape measure lol. He's not a baby though. If I had to guess I'd say he's about half grown. I also just got him a new viv and it's taller, so he's further away from the heat lamp which I think might be the problem because I live in New York and it's pretty cold. Ive tried raising his basking rock but I can't get it any higher. I'm really at a loss about what to do about his lamp and I'm pretty worried that he's too cold. I don't think it's him getting used to the viv because when I got it last weekend he was still pretty active.
