Terrariums for first snake owners?

Thank you so much for replying back to me!

So if the snake is about I wanna say, 8 inches long - would it be okay for me to use a 10 gallon tank for them? Also how do I find out about the sex? I want to obtain a male as I am not looking for a large female later on in life (i heard they get to be quite large). And if the sex can not be found at a certain age - what are the common ways I can found out about the sex?

And got it! Towel or newspaper.

And would you recommend using a Heat Slip UNDER the tank? Or a Tank lighting warmer?
