I have just recently obtained a bearded dragon with what I am suspecting is yellow fungus? I've been keeping reptiles for many years now but, I am new into keeping beardies. He has correct husbandry, 100 degree basking spot 80-90 degree ambient temperature. 55 Gallon tank by himself. He eats dubia roaches and superworms, with veggies of course. So is this yellow fungus or possibly something else. He has yellow on his beard and part of his lip but non anywhere else on his body. And help would be appreciated he is very sweet and I'm the third owner. Thanks for your time.
