I change T. marcianus for another rat snake

Hello, I am offering a nice piece of T. marcianus, bred from the Czech Republic, it is used to pieces of thawed fish (I can add a few pieces of frozen fish to it). Fed twice a week, without any problems. I will gladly exchange it for a black snake, 2 red classics or a coral (NOT a getula). The reason for the exchange is that I plan to focus breeding on offspring and not only on species as such. Only in person Prague, I do not send or drive anywhere. ONLY IN CZ
