The small white spot on one side and few small spots on another side has grown into a large gaping hole infection? What is this?. He is having a hard time breathing and swimming now. It seems to have spread from one side to the other almost as if it is eating right through his body. I don't think he is going to make it through the night but I would at least like to know what is killing/killed him. Please help with any treatment options, similar experiences, ideas as to what this is or links. Thank you.
