GFP Golden lucy?

[Katieduda]

Hi! I have baby axolotls and I took out this Lucy from the tub because he was getting bullied. I was examining his injuries and I found golden nuggets on his tummy! 2 out of 3 of my little lucys have it! I don’t know exactly what to call them. Anyone have this before?

If they're gold and shiny they're iridophores, you'll see them on lots of colour morphs I think to test for gfp you have to put it under blue uv light.
