hi, i've had my fence lizard for about 3 years now, and he is starting to get a bulge in his tail, and he's having troubling excreting feces. also, i've noticed lately that his right eye is swollen. he will sit there and it will look kind of like a cartoon, because his eyes will fill up with air and puff out, sometimes he opens his mouth for a second when he's doing this. his eyes will go back to normal, but now his right eye is larger than normal,making his eye look sunken. what should i do, he is in a 30 gallon tank w/ calcitrate sand or whatever that stuff is. there is UV full spectrum lighting and an incandescent bulb for heat. What should i do about these aliments, there are no vets able to treat lizards in my area. please help.
