Strange though, as he doesn't show any other signs of being a marble. Looks like a form of hypopigmentation(think like vitiligo in humans, but for a fish) but he could just be a weird marble! Maybe it was caused by just some dumb luck and part of the gene for marble just activated. It's strange!
I'm excited to see if Duckie changes. He already looks interesting, has a couple tiger stripes on his back, but if he decides he wants to look different, that'll be fun too!
