Hello, I just got a new ball python and I'm new to this. She is about 3 feet long and 3 years old and I have her in a 40 gallon terrarium. I just wanna know if there is anything any of you would suggest I get or need. I'll attach a picture of my set up and snake in this post. I fed her 1 frozen/thawed white mouse Friday. The temp is usually at around 85-75 and the humidity at 40.

Here's a link to some pictures of the whole setup, where the snake usually is, and a picture of me holding the snake

(sorry about the window glare, her terrarium is in front of a window)

Do you guys have any tips, concerns, helpful comments, or anything I need to know about owning a ball python?
I know she's not a cool or unique morph but I think shes pretty cool
