Regular champagnes come in very clean versions and also versions with circles or other markings down the dorsal. Thus, albino champagnes will come in very clean versions and also versions with circles or other markings down the dorsal. Albino won't change the pattern, just the color. Since the albino parent has a very clean pattern, it makes sense that the offspring might have a cleaner pattern than the champagne parent. Although the one pic of the babies is too small and less than perfectly in focus (at least on my monitor) to be very certain about anything, I bet those 2 turn out to be "just" albino champagne.

The third baby is the one that interests me the most. It doesn't look like it is just a champagne, although I'm not 100% certain how many pre-shed champagne pics I've seen, so maybe they just look like that. I've not seen one in person.

Even if there is nothing else going on, what a nice surprise that your champagne was het albino!

Looking forward to seeing updates. I always love these mystery surprise type threads.
