I adopted my dragon a year ago and he's been great! He was on sand so I put him on slate. But he runs around so much that his nails are super short. One on the back started bleeding and he won't leave it alone. I got him to sit on my chest for a few minutes but he otherwise has not stopped moving. If I put him in the tank then he wants out, and the. Runs around on the floor until he gets cold and I have to put him back in the cage.
