My oldest and biggest koi keeps laying on the bottom of the pond and rolling to one side. I'm terrified I'm going to lose him. From what I've read, it sounds like he's got a swim bladder problem. I've checked the water parameters, PH, ammonia, nitrates and salt levels. They aren't perfect but not terrible either. I've done a partial water change while feeding him some cooked and peeled peas. What else can I do? I don't want to lose him.
