So my Wife and I just got our first beardie, Mal. We love the little guy, he is about 4 months old. We put him in his enclosure and he seems to like it. Spends a lot of time basking and running around. He ate right away. Chases his food and has eaten everything we put in there without a problem. He has stress marks going down his chin and belly but I am hoping those are just relocation stress marks. The Question I had though was about his gaping. From what I have read they do this to regulate heat but he does it a lot when we come near him or when looking at us. It is kind of cute because it looks like he is smiling but I wanted to make sure we weren't freaking him out. He doesn't have problem with us handling him and doesn't run from us. Just the weird "Open Wide" when we come up to the enclosure or when he even looks at us from across the room. He does it when we are holding him too and he looks at us.
