Bearded dragon spikes on side yellow??

[ZeeC]

Hey all! I was giving my Charlie a bath today when I noticed the spikes on the side of Charlie's body are yellow while the ones on Charlie's head is white. I've been noticing stress marks a lot on Charlie that don't go away. Any diagnosis to what could be going on with Charlie?

Could be a colour change which happens, however there is such a thing as yellow fungus which would require diagnosis and treatment by a vet.

Perhaps compare the areas to examples of yellow fungus just in case.

Hi there. just post some better pics in good light, pics of both of his side areas. It's probably just color but you want to rule out Y.F just in case. But a light cream/yellow color of spikes is pretty normal in some beardies.
