You can always insulate a glass tank (with all sorts of easy & cheap materials) that add privacy as well to the back, sides, part of bottom (don't cover the
UTH) & even partway on the bottom-front if you like, just leave a big "picture window" on the front. This will help keep warmth inside & most snakes appreciate
the privacy too. If you want a prettier look, install scenery first, then insulate behind it...you can use foam board, poster board (has rigid foam center), corrugated
cardboard, peel & stick carpet or cork "tiles", thin cork (sold on rolls for making your own gaskets & such, or maybe in a craft store), etc. You can be creative when
keeping snakes as long as what you use is safe & healthy (if in contact w/ snake). Never use tape of any kind INSIDE though, where the snake can touch it...as the
heat &/or humidity can make it loosen, then stick to your snake with disastrous or challenging (at best) results after your snake uses the heat source to "hot glue" it
to himself...ask me how I know, lol.

This is why we have a forum: shared experiences means sharing what works & what doesn't, & we all want to help prevent mistakes so you & your snake have an
easier time. So don't be shy, if we can help you, just ask?

I'm sure the snake you're adopting had very good reasons for being labeled a "biter" before...fear & stress makes for a defensive snake, can't blame them one bit.
Seems you already understand that, so I have a hunch you'll do great.
