Yellow spots on beard

[Munch the beardie]

Please help I’m worried that my beardie might have yellow fungus let me send pictures

 

[xp29]

It's just his natural coloring

I agree with xp29, that's definitely natural color. I've had dragons with full yellow/orange beards and others with a touch of color , if you search the forums or internet for beardies's with yellow beards you'll see many others. So no, your beardie 100 % doesn't have Y.F.
