Thanks for the links, Tony! Like I said, I saw them at an expo, but they were really small. They were listed for $70, I think, a lot less than the members were discussing in the thread that you linked to. A little gross looking as an adult, but still cool.
If you go to one of this links above, members of the other thread were discussing how red color may accumulate (either in albino's or leucistics, I can't remember) since it is introduced in diet and is not a natural endogenous pigment. I don't know enough about these animals, or pigmentation in general to comment on how true that is. So, maybe it is possible to order one with a red belly!
