My Goldfish, Sponge Bob is about 5 years old, its went from a fry rescue to a somewhat regular-sized goldfish that jumped out of the tank twice in its lifetime, once in its infancy that I was able to toss back in right away, the second time it jumped out it was during the winter of 2017 where I found it on the floor for an unknown amount of time on the floor when I found it. I was able to toss it back in and put its mouth onto the water pump to get it breathing again after a few hours it was swimming around wobbly but it was alive. Now it’s gotten swollen and listing forward and losing its ability to stay upright. It stays inside the terracotta plant pots to stay upside. when it swims around it has a hard time staying up and tends to go belly up, it rights itself most of the time when it eats. Is there any hope it to be healed or to make its life as comfortable as possible.
it has 2 other Goldfish.
