I have two questions about my bearded dragon?

I'd like to see a pic of it. Is the yellow in patches or splotches or is it even and symmetrical? If it's just patches I'm afraid it could be yellow fungus. However, if it's been there for over a year and he still is eating and acting normal...maybe not. It would be a good idea to go to the vet just in case. Better safe than sorry. Yellow fungus on the skin is treatable, but if it goes septic, you will have one very sick dragon. Please take some pics and post in the ER section of a href="http://www.beardeddragon.org" rel="nofollow"http://www.beardeddragon.org/a for better help!
