Alright, there's a picture at the bottom of one of my goldfish who seems to be displaying some unhealthy signs. They live in a pond outside and it is important for their survival to hide when things go near them. So I see this lil goldfish in the shallow end of the pond by itself, not really moving. I look closer and it didn't swim away, it is alive and breathing. It only moved a little when I put stuff right beside it. If I don't help it fast it's going to get picked off. What can I do? The other fish are fine and healthy (I have pics of them too!) but I would like to save this one if I can!
