Like SinLA said: You need two separate enclosures. Tortoises should never live as pairs.Thanks lots of helpful info. Can you point me in the right direction to get into on what is best thing to do for my two Hermann who have a large heated enclosure that are from the same breeder from the same batch that I have owned for ten years but have now started to follow one another around and mounting each other. I'm very attached to both of them and they have lovely characters so getting rid of one isn't an option.
