Hello, which species of tortoise do you think is the easiest to breed indoors? I have a whole room of my home i can dedicate to a species of tortoises but I must be able to breed them indoors, I would be able to house them outdoors for part of the year I guess, but my backyard is made of asphalt so I would have to construct a cage for them. I like russian tortoises because of their small size, but would try other species or a few species at the same time. Thanks for your help. What are the maximum sizes of sulcatta and leopard tortoises? Thanks.
