This is my male leopard gecko. The first pic was taken of him in February and then the last picture is him now. He did seem off for a bit but he seemed to be wanting to mate at that time and now he has slowed down. He has lost weight and his yellow has gone away. He’s pooping fine but eating less. He has an under the tank heating pad as well as just a heat lamp. His tank stays about 85 F and he has a cool/moist hide along with a dry/warm hide. His tank is 10 gallons. He is fully aware and does not seem lethargic or like he’s in any pain. He’s still out a normal amount of time. I am just curious as to why he has started losing weight and his colors aren’t as bright. I know they can stop eating during mating season or if the seasons are changing but he has also been having more trouble shedding. I keep damp moss in his cool hide for him and his substrate is paper towel. Also, I know their colors can change when they shed but this seems like a big color change to me. The nearest vet that will take him is out of state so I have been trying to baby him a lot and see if he gets better on his own. I’ve been cleaning his tank more often so that I don’t have to worry as much about bacteria. All of his food is dusted with calcium and vitamins. He is the only gecko in the tank. He’s the second leopard gecko I have had and I have never had problem like this with my other. Please give me any advice you can. thank you.
