I have a 2 year old beardie whose name is Ernie. For about a week now he's been very active such as jumping off his perch and running around his tank, I'm worried because he usually just suns himself and sleeps the day away usually. He as been eating a lot more lately and i let him drink and run around but he keeps banging his nose against the wall. I'm worried somethings wrong with him, please help!!!!!
