So, I was told that the black markings under a bearded dragons jaw, or on his "beard" are a sign of stress. now he doesn't puff out or hiss or anything like that. But most of the time when he is in his tank, he has those marks and his back gets darker as well. The only way I can get him to lighten up is when I'm holding him or he is eating.
Is there something in his tank that's bothering him, or is he just naturally grumpy?
