Natrix helvetica ( or another natrix, not sure on that one )

Sorry Snaky, I'll have to correct you. Steven Bol has T.radix and T.s.pickeringii (not infernalis) in his outdoor enclosure.

I know different subspecies can make hybrids quite easily, but as far as I know, it didn't happen to Steven so far.
I'll suggest you should contact Steven about that.

ps. Sjoerd, next time you have to join our meeting, than you don't have to ask questions like this
