we have 6 beardies that are between 4 and 5 months old. they vary in size, but the largest, and seemingly healthiest one died last night very unexpectedly. my son called me in because he thought the dragon wasn't breathing. then he seemed to be gagging, or at least his mouth opened very wide, his beard puffed out and was black. he did that and would go from running around like crazy, and then he got completely rigid and still. he did the gagging thing several more times, and would alternate between being rigid and then loosen up. within 30 minutes of noticing his strange behavior, he was gone.
my son and i are very upset about this, and don't want anything to happen to our other beardies.
does anyone have any thoughts on what may have happened?
