Hey Everyone!

We just bought our first tank (So flipping excited) and we're gonna work on the set up for a week or so before buying a snake. I've read about covering up the sides, and I'm going to, but I have a question about the back.

Our tank is right against a white wall, so there won't be any movement behind it what-so-ever. Should I still cover up the back, or should the plain jane white wall be ok?

Thanks in advance!
