Hello and welcome. My name is ***** ***** I'm a biologist with a special interest in fish.It sounds like your fish is suffering from swim bladder disease. The swim bladder is an organ that enables the fish to properly orient itself in the water. When something goes wrong, the fish may float, swim upside down, sideways, or at an angle.Constipation can be a factor, too, if unpassed droppings press on the swim bladder. An injury could also be responsible. However, sometimes a swim bladder disorder just crops up for no apparent reason.It would be best if you can isolate the sick koi in a hospital tank. A large tote, such as those made by RubberMaid will work well. Use water from the pond and set up a filter or pump with an airstone. Once there, there are a couple of things that may help the ailing fish. If it will eat, give it a couple of thawed out and peeled frozen peas. The peas can sometimes get things moving again, and ease pressure on the swim bladder. I would also add one teaspoon of aquarium salt per gallon of water. Don't use table salt - it sometimes has toxic additives. Keep feeding nothing but the peas for a few days.A simple method that works in some cases is to simply not feed the fish for 4-5 days, while being kept in a hospital tank with salt added. Swim bladder disease has different causes, and therefore a certain treatment may work in one case and not another. If you choose this method, do still add the aquarium salt.If you want the best possible help for your fish, you may want to consult an aquatic vet. This link will take you to a directory of such vets: an underlying health condition leads to the swim bladder problem and a vet would be able to assist with diagnosis and treatment.
