Thanks evryone
I have ordered it now from NHBS(Ithink that's the name). If it has some info on paramesotriton&pachytriton, even if very little, it's good enough for me - Ican't find anything in books except, "The paddletailed newt, (Cynops Ensicauda) is a very difficult species to maintain, as little information is available on it". I will keep the book annonymous...
