That's pretty cool, I'm interested in seeing it after a couple of sheds. Sometimes it's not so much that they're axanthic as they're "faded" in color. In recent years you see it most often with Albinos, they look almost like snows until after a couple of meals/sheds and they color up quite a bit but still not quite as bright. Red "Axanthics" do something similar.
Regardless though it's definitely a awesome animal and it's always nice to see a surprise like that!
