That is much better than I had in mind (I was thinking shorter-style tub only a few inches tall). It is still a bit big, so make sure to clutter it up with hides and such like you have. The key to keeping little ones successfully is making sure they're feel secure and comfortable (which means appropriately small, dark, quiet, warm, and humid). A heat mat and thermostat combination will definitely help out once you get that up and running.
The other thought I had is make absolutely sure your little one can't escape. Not sure exactly how the screen is secured, but if there are any weaknesses at all, your new addition will find it. They're little Houdinis!
