Over past few days my beardie has been acting very odd...his beard is quite black for most of thr day. Hes been pushing himself up against the glass and scrathing at it rather vigorously. First time did it i opened tank and he jumped out and scoured the room for a while. But his beard was still black. And keeps trying to climb my wall and door. Even after back in hes still all black bearded and does the same. I cant understand whats wrong with him :/ hes eating fine and all that so just so confused. Any help would be more than amazing thank you
