I'm finding that you can keep almost any tortoise together depending on the setup.
I've got sulcatas and redfoots in the same yard. They are not together because that is what I choose to do. The environmental conditions they are exposed to are identical.
The two species selected in this discussion are probably some of the most adaptable tortoises I've come across. There are others but these are the more common.
Keeping 2 captive born hatchlings of the two species should not present a problem until the Sulcata outgrows the RF.
>>microclimates are where it's at, I just think (and this is just my opinion) that redfoots and sulcatas are different enough in care that I wouldn't attempt keeping them together.

>>Good points though. This is an interesting discussion.

>>Oh, and by 'dark ages', I meant going back to the days when everyone thought that the same setup would work for practically any reptile that would fit in it. I wasn't really commenting on the idea of keeping more than one species together.
