Sounds like you're already addicted. Invest in a rack. Newbies are always concerned about lack of space, but remember: BPs live in termite mounds, crammed into tiny spaces, and they're happy that way. A rack tub is a perfectly regulated, dark hide so it's perfect for BPs. You can build another tank setup if you want, but a rack is more space-efficient and that means you can get more snakes in a smaller space.
