Re: the rankins dragon colors. I was told that the only true to natural color is the dark gray/green, and the reason there are so few rankins in the USA in the pet trade is that because Australia put the ban on exports relatively quickly after they were identified, and most of the stock in the USA is from the original few pairs that were smuggled into the USA. In the 80s, these Rankins were interbred with small beardies to try to strenghten the genetics, and then bred back to the Rankins, which is why you sometimes see lighter rankins in the pet trade, or lighter rankins with shades of red, orange or yellow. A majority of the rankins in the pet trade are still more rankins than beardies, but there are some muddy genetics 5-10 generations back which accounts for some of the color variations you see in captivity that don't appear in the wild.
There is a lot of hubbub amongst breeders of what constitutes a true rankins, and what is a vittikins, since pretty much all the breeding stock available is muddy... In my opinion if it has the tie pattern, no beard, and stays small its a rankins
