Well, a couple of weeks ago I noticed that my leopard gecko couldn't see when I was putting food right infront of him it is like he is blind and reacts slowly. I have him in a 10 gallon tank soon during Thanksgiving break I will be getting him a 20 gallon since he is an adult now. I have a calcium dish without D3 in his enclosure and he has water and I feed him superworms (gutloaded with carrots and sometimes apples) since that is what he pikes since the breeder I got him from feed him supers. He has a moist hide and one cool hide and one warm hide. The warm side of the cage is about 92 degrees and the cool side 79-85. I don't know what to do? I don't know if he is going blind or what? Any help would be greatly appreciated. God Bless - Moefv
