Hi there....it's probably [ hopefully] just a patch of shed. See if it will come of with gentle strokes from a soft toothbrush during a warm soak. He's a cutie pie.

Thanks You ? I'm just getting concerned since I discovered yellow fungus during my research :/ I hope that's not the case and I will take your advice. I hope you're right! I'll let ya know how he turns out.
