When talking about smuggling I'd say they are in the same case as many dart frogs. Some come in legally and some might be smuggled. Why post things like "I think they came in illegally ... I think they are CITES II. Why not check out your guesses and post them as facts. I was interested in salamanders that some guys "Thought" were cites restricted. I checked the CITES site and they aren't. I purchased the legal salamanders.
I know of at least 2 reputable breeders breeding Theloderma. The first time I saw these frogs posted they were over 400.00 each. Now they are down to 125.00 for a froglet and 50.00 for a tadpole. They are hardy and easily kept. I'd say that's an accomplishment and not something to be second guessed and naysayed.
