I just got 3 bearded dragons last week at a reptile show and one of the three was a little smaller than the other ones but they were all in the same enclosure. The two bigger ones are like 5 inches and the smaller one is 4 inches. The small bearded dragon, spyro, has been declining in health the past few days, it seems. I have separated him from the other dragons because of this issue, but he hasn't been eating for the past few days. He doesn't really move much at all in the aquarium that i have him in and he just sits there with his eyes closed a lot. Another thing that worries me is the way that he acts when i pick him up to look at him. He always jerks his head back and tries to move by doing that while i am not restraining him at all, he just keeps jerking his head. He also just rolls off of my hand sometimes instead of stepping off. One other behavior that has me concerned is the way that he moves in the cage; when he moves, he doesn't even pick himself up off the ground, he just kind of drags his belly on the ground. The lights and heat in the enclosure are by the book. I am using a reptisun 7.0 and a 100 watt basking lamp with a 109 basking spot. I don't know what is wrong with my dragon and i need help to bring him back to health. I didn't really want to go to the vet with this because of the expense, but if that is what i have to do then i will. PLEASE REPLY!!
