What are you using for substrate? I always recommend putting new snakes on paper towels because if they happen to have mites you can see them a lot easier on paper towels. Also, clean up is easier and you can monitor bowl movements to make sure they are normal for a new snake and you don't need to worry about them ingesting any substrate if you plan to feed in the tank (have it be f/t or live).
Congrats on the new addition!
