I have two bearded dragons. They are about a year old. They each have a 75-gallon tank. I have a 150-watt basking bulb and a reptisun t10 uvb. They have been doing awesome and all of a sudden they seemed to quit eating their vegs but still eat crickets and roaches. They act like they are going to brumate. The male more so than the female. I just want to make sure I have enough UVB lighting in the tank for them. Do I need two or some other set up? What kind of lamp should I have my uvb lite in? They are actually my grandsons but it seems like I am the one taking care of them. They are so sweet. I just want to make sure I am doing right by them. Any advice would be appreciated. I have digital thermometers in both tank. The temp on the basking is right around 100 and the cool side is about 75. I have the uvb in the middle of the tank. Not too long ago I had their poop tested and no parasites. But they just aren't as active as what they had been. Thank you.
