ok i have a lil story i know this might offend some of you. well maybe all of you. but my friend rescues a bp and a cornsnake both about 8 years old so the lady said and have been housed together all there life the bp stays on one side the corn on the other and they dont bother each other we split them apart in there own enclosers we had them sepertaed for a month and both of them wouldnt eat. then we put them back together. and a week later tried feeding and they ate. so we keep them together. i know we shouldnt but the bps requierments are met along with the corn snakes requierments. the tank is a 75 gallon breeder custom built
