You really should consider housing them in separate racks altogether, imo. The bp is a tropical temp species reptile where as the corn snakes are temperate species. Their flora and fauna is very different. Then mostly, your racks heat tape wattage will be different depending on the size of the tape as well. 3" as opposed to 6" tape or 11". Yeah, some thermostats can handle different wattages of tape for varying heat zones but there is a safe difference that you should check with the manufacturer on. Good luck.
