He had nice adult P. waltl and yes he had many axolotls.He also had a tank crammed with Cynops.He may have had more but I was talking with him before the show opened so he could have put more on display later once it opened to the public.I don't remember seeing any sirens, just amphiumas.And the guy with the eletric eels,lungfish,etc. had a tank full of aquatic caecilians.Not really suddenly, I've seen full grown amphiumas there before and I'm sure I've seen sirens.There were not as many salamandra as usual.If you were referring to the baby CB salamandra those were mine BTW. =)Oh and when I was talking to the caudate vender we were discussing the "croc newts" and he said they were paramesotriton too.As for the species that make it into the U.S. market I have no idea.
