I'm in the design stage of building a 2' X 6' indoor enclosure for my pancake tortoise and I will be getting an Egyptian Tortoise soon. The pancake is still a baby and the Egyptian will also be a baby. I want to temporarily divide the enclosure so there will be 2 @ 2' X 3' spaces in one enclosure. Since one is not suppose to house two different species together my question is how close to each other is too close? Many viruses and bacteria are airborne and I would hate to get them sick from being too close to each other. Should I house the Egyptian in a totally different enclosure or will they be ok next to each other?
