Yes my wild type started out with a creamy belly but now it has changed to a blotchy-grey underbelly. He is also growing faster than my albino and seems more predatory lol.. I have a more olive lighter color ACF who has a creamy belly but no blotches sooo i don't know, it seems to vary a lot.

Does it look like this?
