I'm very sure that your animals are import animals from Kongo. I saw much photos where Mediterranean species so testudo gracea marginata hermanni are mixed up with species like testudo kleinmanni. So the seller bought your animals as testudo gracea but he hasn't enough knowledge to see that he has kleinmanni.
There are many couriers and animal relocation companies that would do it within the EU as it is not that hard, if you were interested. Heck, I'd even be interested in it if you wanted to.
I know that you really want one of them to be female, and I know that one of them seems like they have a smaller tail, I just wanted to show you what my female's tail looks like. This is a Boettgeri.
The guy from Italy makes tours sometimes. He or his friends drive in Europe from country to country. One year ago I bought three kinixys homeana from him and we meet in Germany 50km away from
Me and he comes from Italy! So to get the animals isn't a problem. To send them to the guy if you can't meet anywhere isn't a problem to. You hear there many good transport firms!
I think I got the oportunity to exchange 1 of the males with a female from the same guy... Problem is I have to choose the female my self give me some guidelines fast how to be sure shes a female and which one shall I exchange the big or smaller one? thanks!
