Well... About a week ago I came home and my tokay gecko was dead... I don't know what happened to him so I'd appreicate of someone could give me a diagnosis to make sure it doesn't happen to my female. I was pretty horrified when it happened so I might not have noticed all the details. 1) He was stiff 2) He'd been dark colored for a while but was brightly colored when I found him 3) Stomache bloated 4) Eyes seemed to be sunk in 5) He had been eating and pooping 6) Black cuts on his back... My mom said it looked like the skin split... 7) he had never been overweight 8) Couldn't climb on glass walls 9) Making more or a shrieking instead of croaking noise when I would grab him 10) recently had eggs with my female 11) had been acting like this ever since I switched him to his(much better and cleaner) tank He is also originally wild and may have had parasites but he's never acted odd before. We don't know how old he was. But he was full grown.
