First of all, what was the name of the shop? I live in the area so just wondering if it's the one I'm thinking it is.
Congrats on your new pet. My first concern, now that the tank is clean, would be getting the humidity better which will help him get the rest of his shed off and have good sheds from here on. The number one thing you can do to get humidity up in a tank like that is to cover as much of the screen as possible. When I used a glass tank, I cut a piece of plexi glass to the size of the lid just leaving a small gap for air but if your going to use the heat lamp(also terrible for holding humidity) then you can't cover where it sits so you'll need to leave that area just screen. You may want to look into an under tank heating mat and ditch the heat lamp. You should have a thermostat either way but you absolutely must have one if you use a heating mat or it can get hot enough to burn your snake. Other than those couple things, this tank will make a nice home for him.
Overall, it sounds like your giving him a much better life![]()
