Ive been trying to upload a .jpg photo, but it keeps saying "invalid format". Anyways, nothing looks physically wrong. He is just floating with all 4 extremities out wide. I wouldn't say he has a disease. He just was out of the water too long. I don't know if he will get better, or if there's something I can do, or if I should euthanize him. I was shocked that I couldn't find anything on Google. All I found was that they will die if left out too long...Nothing about trying to save them after they have been out of water awhile...
