This is John Gibeau of Tincs.com. I have produced two clutches of eggs from my castaneoticus, and all were bad. I have a group of six, as Alexander said - The only person on this forum that knows my collection better than he does is myself.
First, the United States Fish and Wildlife does NOT selectively set dart frogs as legal or illegal. They are all (Dendrobatids, Phyllobates, Epipedobates, and Minyobates) a CITES II animal, and therefore legal to bring into the country. As long as there is paperwork fom the country they are arriving FROM, and that does not have to be the country of origin (It is actually easier to get WC animals than it is CB animals, because the WC animals have pre-existing paperwork most of the time)F&W will stamp them every time, and not say a word. They do NOT get involved if an animal that is in the country legally under paperwork contract, like A. zeteki from Panama, gets into the public and breaks the contract that the country of Panama has with the AZA - The AZA simply has to deal with the legal issues of getting sued by Panama, and not getting animals from the country in the future. F&W will not start going around trying to collect up the frogs that are in hobbyist hands because technically, they are legal - They came in on a 1077, which is all it takes. All contracts beween host country and reception country are between them.
It was mentioned that D azureus are illegal; this is not true. They came into the states under a 1077, I believe to the Baltimore Zoo and Aquarium, and offspring were traded away to the private sector for a different species of frog. Suriname got really pissed, but in the end could do nothing, because someone left out the "no release" clause in the contract. Just like human babies; if it is born here, it lives here and that is that.
I hope I have cleared up any problems there might be with whether or not Alexander Stubbs knows the content of Washington State frogger collections, whether or not I have bred castaneoticus, whether or not Todd Kelly has castaneoticus, (he does, and LOTS of them) and the legality or lack thereof of castaneoticus and azureus.
