Going from that huge glass tank to manage to putting each snake in it's own nice plastic tub is going to make your life so much easier and the snakes so much happier in the long run. You won't get the display properties that a glass tank offers but BP's aren't a great display snake anyways as they tend to be in their hides a lot. Really boring to have friends over and they peer in a tank and see a coil stuffed in the entrance of a hide and that's about it LOL

You could find a lot of other nice critters that would love that big glass tank I'm sure and for a very reasonable price get Dude and Monty into there own seperate homes.
