One of my beardies--the biggest (about 10 inches total length) showed no signs of parasites, his feces looked fine, he was defecating regularly, had no outer wounds and no signs of illness. I was at the tank looking at him sitting in the his basking spot happy as ever and 30 minutes later I went back to the tank and he was dead. The only odd behavior that I had noticed is that he was sitting with his mouth open alot recently. Can anyone give me any answer or possible answer as to what happened?
