Looking for Thamnophis tetrataenia/similis/radix/eques

I'm looking for females of

- Thamnophis tetrataenia (I'll also buy pairs or groups!)
- Thamnophis similis
- Thamnophis radix anery
- Thamnophis eques obscurus

Adult animals preferred but I'm also interested in younger ones.

I'm in Hamm and Houten.
