My bearded dragon is about 3 months old. Ive had him for about 2 months. I’ve posted about this not to long ago. I didn’t get any posts on really how to stop him glass surfing. I can hear him doing it almost every time I see him. He gets out for about an hour a day. He has a 20 gallon tank which is ok for now. In 5 month at Christmas I will get a 75 gallon with a screen door. I wish he would stop. I don’t know why he does this. He will run back and fourth from one end to another of his cage!
