When I first was getting a tortoise i didn't know if I should get it from petco or not, but I started visiting more regularly and he was always walking around and always had the vitamins he needed, but I wasn't sure if he was sick. But, eventually I bought the tortoise and now I have had him for 5 months and he seems happy as ever. So I don't really know if petco has the best tortoises, but I really like the one I needed up with.
