So sorry for your loss dude
And after all that we went true. I did the best I could to help you and to interpretate the simptons you were giving us. I honestly though he would make a come back
Sugestion: try another comon snapper but the next time get a bigger animal, a subadult would be ideal and near bullet proof
Dont you have like a local rescue society or something? Give a homeless snapper or another turt or reptile of your liking a good home
