Watching his/her behavior, like Cooper said, is a great idea. I have 2 beardies, Spyro and Ember. Spyro was crazy when I first got him. He liked to jump on the screen and hang upside down. He would do this for a few minutes, rest a little then start back up. So I call him my Spyro monkey. My other munchkin I let my son name. He chose her name because she has red, orange spikes down her sides and some of the same color patterns down her back and tail. Good luck choosing a name!
