I have a vail chameleon who is acting weird. It started a week ago his UV light not sure if it's UVA or UVB blew out. It was soon after that we noticed he was keeping his back right leg straight and had issues grabbing anything with it then it went to his other back leg then to his front legs. He does not move a whole lot and when he tries to reach for a branch his right front leg will go up over his eye and he will like grab around his eye he's been eating a little and I have been giving him water in a dropper as well as spraying him with a sprayer. We have found him several times on the bottom of the cage. And we have found him hanging from just his tail upside down he's been eating a lot of crickets and mealworms that we coat with his powdered vitamins. He has been dark in color a lot too. Please if you have any ideas please let me know what to try. Thank you
