That's close to how Gizmo looks. He normally doesn't have a
black beard with them, only when he eats or I accidentally wake him up. At night they are barely there and he is a darkish brown with light brown markings. During the day he changes his colors on the activity he is doing. When he is eating he's sort of a blackish brown, when he's "sunbathing" whether on my shoulder outside or under his heat light he's a dark brown color with those marks. Now when he gets a
bath I know those are stress marks as they are very dark and he has a
black beard. The water is warm, the same temp I use for my ball python, he just doesn't like them currently. As soon as I take him out he lightens up. Those marks are always there though so I was simply curious about them
