I hear the word "temperature gauge" and I am picturing those round dial stick on things. If so, trash them. They are so far from accurate you will be amazed at what your temps read with a digital thermometer.

Your temps might be warmer than you want, so please be sure to get a digital thermometer and hygrometer so you can get a more realistic view of your temps and humidity.

As for hides, I've seen people use the half log hides, but I think the ball pythons would choose something more snug (like a rock cave) over the log.

and good luck with your new baby! Any pictures??
