I've been through what you are describing Steve, about 10 years ago when I knew next to nothing about "exotic" newt species. I got Paramesotriton instead of Cynops and I was mad at the pet shop. They took them back and gave me a refund. In retrospect I think if that happened again I'd keep them. Certainly, if I could keep paddletails I might keep them too. For me now this is rhetorical because I refuse to buy anything that's wild-caught. I'm against the mass collection and mass death of Asian newts, and I don't like to encourage illegal collection of European species either. When you see 19 adult Tylototriton (shanjing and kweichowensis) die slow horrible deaths due to side effects of importation, it will break your heart.
