Stefan,
If I had a N. natrix I'd definetly trade you for tetrataenia, though as far as wishing goes.
Yeah, its ironic what we are allowed to keep sometimes; Ex. in Oregon you are allowed to have all Bitis except arietans, or your also allowed to own a King Cobra but not a Egyptian, or your allowed to have a Bushmaster or Lancehead but not an Eyelash Viper. Though, depending on where you lie in Oregon you can have just about any boid or colubrid which is nice. Sadley, one other euro herp I like are Lacterta lepida and they are also illegal but there is more of a reason for that restriction (since temperate lacerta have already become an introduced species to Vancouver Island, British Columbia).
Ok, I'll cut down that list. Does anyone know any breeders of;
-T.s. pickeringii
-T.s. infernalis (I know Scott Felzer does them and similis)
-Nerodia rhombifer (I've seen people breeding amels but not really any normals)
-Natrix tessellata (I've seen a few people sell these but I think they are WC)
Thanks and Sincerely,
Mark
