Hey, everyone! I'm new here so here's a super quick background. My brother and I had a BP when we were younger (like almost 20 years ago) but had to rehome it when we graduated and moved out of our parents' place, so I'm not completely new to snakes, but might as well be. I recently started researching so I can get another one. I've since learned that we knew next to nothing about snakes but I'm more confident now with my newfound knowledge. That said, here's my question...

Can you have too large of a tank for your snake?

My initial plan was to reuse my old 10 gallon fish tank. I went to the local big box pet store to get prices for supplies only, not snakes, and saw that they had one of those reptile kits with the substrate, hide, water bowl, uth, etc, along with a 20 gallon tank on sale for what I feel is a pretty good deal. I know the snake will outgrow the 10 gallon eventually and I'll need to upgrade, so should I go ahead get this good deal or will a 20 gallon be too big for a baby? I read that you can add some more decor to make it not feel so open and they'll be fine. Is this true?

Thanks in advance for any help! This forum has already helped me a lot as I was lurking waiting for my account to be approved.
