Hello all. We recently got a new Redfoot. It appears it has shell rot. I just treated it with iodine, then wiped it off. I then applied some antifungal cream. I cleaned the enclosure and I am getting ready to put new substrate. My question is the new tortoise is in the same enclosure with another one. Should I separate them so the other one does not get it as well? I'm just worried that if I have to separate them that I don't have proper lighting for the other.
