We rescued a large size bearded dragon - not sure of the age as it was donated. One side of the tank is 120 but I understand it should be 110. I have read things that if he seems ok, the temp should be fine. He seems to like it and still active in the tank. However, twice now he has had a little bit of blood in the stool. We know that lighting/heat is key. Should we raise the light more so that maybe it does not get so hot? Also, how do we regulate to make sure the other side is 80 degrees in the cool spot? This is a very large tank 30x12x12 tank. Thanks for the help
