Thanks to everyone who answered my many questions after I somewhat suddenly became responsible for a bearded dragon. Unfortunately, he died today from a systemic infection of some sort. He had been to the vet five times in the last four weeks for exams and meds and injections and blood tests and oxygen, and I was told today that it was time to let him go. He was one cool lizard, and I will miss him. I don't think I'll get another one, but if I do, I'll remember beardeddragon.org as a source of info.
