Congrats on the new dragon! If he has a
black beard, black lines on his belly, or just seems darker in general, he's definitely stressed. But generally moving around stresses them out too, being in a new environment and all. Maybe leave him alone for a couple of days and let him get acquainted with everything. What's your setup like?
After he settles in, picking him up from in front of him instead of above will help,it probably scares him having a giant hand come up from the top lol. Taking him out before bed for some snuggles might help, or a warm
bath.
