Not that I would house different species together, but I am curious about a certain point of housing different species together more particularly captive breed tortoises. I understand that wild caught tortoises carry certain bacteria that are beneficial to them, but can be devastating to others species. My question is: Do captive breed species still contain these bacteria? And if so how do they get them? Say for instance that you have a captive breed Hermans and a captive breed Russian that where housed in similar but separate conditions and feed food from the same sources would they still develop different flora in their intestinal track making them potentially dangerous to house together? Maybe there is a simple answer. I just thought it to be an interesting question that someone here could clear up for me.
