so tonight I just got home from work and my 3 month old bearded dragon named zeus had this waiting for me. its clearly poop because he pooped right next to it. he also poop in another part of his tank. over all he is in a 40 Gallen breeder. and his temps are fine. he has been eating and pooping like normal and I woke him up right now and he completely reacted to me so nothing seems wrong with him but this poop doesn't seem right. he is feed primarily on dubia roaches and when he eats his greens he only likes mustard greens. does anyone have any ideas on what this is?
