Well, I'm not sure. You can find aneries and ghosts in some localities, but they are expensive. Amels are much more common, and are a bright orange. I think you have to decide on which pattern you like, the strongly, obviously striped, like the mexican, (which, coincidentally is also the least terra cotta, even in normal coloration) or the less obviously striped pattern, like Noah. I never could decide on which locality I liked the most, and then I met Noah at Daytona and it became obvious that what I really loved was a blue-eyed anery, who cares about the locality, Noah was the perfect Rosy. Sean Niland has a pretty nice selection, in season. There will be a few at Daytona.
There are only a couple books. Boas Rosy& Ground by Jerry G. Walls has good pics. The rosy section on FC is not much used, but there are some experts there. People with the rarest morphs.
