My ball is about 5 months old now and I have noticed that he is extremely active during 2-5pm time of day. During this active time he is climbing the plants on the walls of my glass tank and always is climbing the sides of the tank and looking up at the screen. I don't think he is stargazing and does not seem to have any respiratory issues or any signs of mites. He has been eating normal and is growing great. Is this a behavior I should be concerned about or is it just him being a snake?
