asking this on behalf of my little sisters friend, who has a bearded dragon thats been extra lethargic and definitely sick (they dont know what it is, though, which is why im asking here for her). he hasnt eaten in around a month at this point, doesnt breathe easily (he sounds wheezy/like hes gasping sometimes), and has a yellow mold-like fungus growing around his eyes and mouth. if anyone could give us advice on what this is and how to treat it, how serious it is, etc. that'd be great. <3
