well i have read that the name Canary was used to hide the location... if they called them by the localty they would have been snatched up quickly... because everyone would have known where they were... the people that were bringing them in must be a little on the smart side... 
also... i have a theory...
i believe that this yellow coloration has to do with that food it was eating... or rather its foods food... much like poison arrow frogs... i have just recently learned that poison arrow frogs are not poisonus in captivity... they get their poison from the things that eat... well i think that the reason that some of these guys are turning green is because the food source has changed... now i dont own any of these canarys yet... nor do i have much to hang my theory on... but i dont think i am off too far in my theory if at all...
if anyone woudl like to hear more about my theory please ask and i'll try to BS my way to an answer... cuz as i said i have nothing to base this off of...
flame away...

>>Hey Rubbadadolphin,
>>I sincerely apologize if it sounded as if i were a bit harsh, for in noway was it my intension. Such is yet another negative aspect of reading true meaning from text alone. So once again, I aplogize if it sounded as such

>>Regarding the various price spectrum on these chondros--there are some differences in them, and many people who have taken a significant amount of time to carefully evaluate them have noticed numerous morphological differences (aside from simple coloration, and health observations). These differences seem to be so clear, that some people believe they can get a fairly good **guesss** on whether or not they will in fact retain their yellow coloration into adulthood. A number of factors dictate the various prices noted on these chondros...much like "high end" designers. But generally speaking, health and over all condition of the animals is a major initial difference. As for the spike in their availability goes....seems to me that those still on the market and those that came into the open market were in fact "left overs".....
