I own one Bp about 16 inches and one Corn snake about 12 inches or so. I currently have my BP in a tank is almost 4 feet long and it is way too big for her. I thought it would be a good idea to maybe divide my tank, give the BP about 3\4 of the tank and my corn the other fourth. My question is what would i use to do this? Has anyone else done this? Do you think this will work\is a good idea?

thanks in advance for any input
