HI. My beardie is 6 inches and has seemed very healthy since we've had him, for about 5 weeks or so. However, today, he just started acting weird. First of all, every now and then, he shakes his back legs. I have not seen him do this once until today, not ONCE. Second, he hasn't eaten at all today. And, third, his poop has a little clearish-yellow bubble thing in it where the white would be. I haven't noticed this before, and I'm very concerned he might be sick, but he has seemed fine besides that. His colors are great, and he's still active, aside from not eating. Please tell me what these could be signs of. Thanks so much, mafu7
