I've had my beardie about 3 or 4 months now and he is usally a happy eater, but today he stopped, or rather, eats 1-2 crickets at meal time. I've included some wheat grass in the enclosure with him just incase, is it something wrong with my enclosure? His basking temp is about 105f and cool side is about 80 and I have all his necessities, thanks for any and all advice.
