I have inherited two goldfish in a small tank . One of them is a black big eyed fish. Sorry, I don't know much about them or what they are called. This fishes name is Joey. A few days after they came to my house Joey had a very long ribbon looking emission. He swam around for a while with this emmanating from his poop shute. It was not poop. After this long (10 inches or more) mucousy looking ribbon fell away, he began to have trouble swimming. He just seemed really heavy. I know now that his swim bladder is impared. I have tried the fasting and frozen pea remedy but he is still heavy, and sitting on the bottom. He does come to the top to eat and his appetite seems good. It has been a week since this happened. Is it possible that his swim bladder ruptured and he expelled it? Can he live without it? Is he suffering? I have read several articles but I am at a loss as to how to proceed.
