Hello CP & welcome!

I think you are off to a great start and made a wise choice by joining this forum. There are three things that I wanted to address by your pics. First, you will need to modify the screen top in order to maintain the proper temperature gradient and humidity levels. If you don't already have one, you should invest in a hygrometer. You can find a pretty decent one at Walmart or Target for about 15 bucks or so. Lastly, what type of heat are you using for the tank? Do you have it hooked up to a thermostat or rheostat? There are some great stickies on the BP Husbandry section.

I am very excited for you and I hope that you enjoy your ball python as much as I love mine.

Take care,

Rachel
