I recently rescued a redfoot from someone who got it from a friend that was not caring for it properly, turns out they have 2 more redfoot tortoises they asked if I want them. Of course I do but they think the 2 others are bigger than the one I already got. How much indoor space would be the minimum for 3 full grown redfoot? Do they get along well enough to be housed together or like Russians would it be better for individual houses? And if individual what's the minimum indoor space for one?
