I have several juvie beardies. In the past day or so one of them has kind of started to spaz out as you pick it up. Its about 3 mos. old. Its head trirls, and it becomes all herky jerky. Once I set it down it will move over to a spot where it can lean up against something in the tank. It then lays motionless. Any suggestions? I know they occasionally will turn into "stargazers" but after this amount of time I'm kind of suprised.
