So my beardie is a 6 year old male and once in awhile he'll run around the tank and trying to like scratch the sides of the tank and climb out. But on rare occasions he'll start head bobbing inbetween which he's been doing for the past 3 days and I just dont know what to do. Hes driving me nuts! I try taking him out for an hour or 2 and hes really calm but once i put him back in the tank he goes right back to doing what he was doing before. His beard isnt black either its normal color and i have a background around the back and sides of the tank. Can anyone tell me what i can do to make him stop doing this? i just dont know what to do >.<
