My bearded dragon Leo is a couple months old. Just recently this past week I have noticed that he has been dragging his body around and not being very active. His back right foot seems a little swollen but he does not seem like it is painful when I touch it. I've also noticed that his stools seem to be a little bit runny. I feed him dubia roaches as well as greens every day dusted with calcium powder. His basking spot is around 108 and the opposite side seems to be around 80 degrees. I use a t8 uvb bulb which i just recently found out to take the plastic cover off of so that the bulb is not being blocked. Both the basking lamp and uvb fixture sit on top of the screen of his 20 gallon tank. I've also noticed he does not want to come out in the a.m. and bask and he seems to avoid me more and go hide which is not normal. Please Help! I'm not sure what I'm doing wrong and I don't know what to do
