Why is your koi getting fat?

Koi are omnivorous fish that will eat a variety of foods, including plants, insects, and small animals. If a koi is fed too much food, or if the food is too high in carbohydrates or fats, it can become overweight or obese.

Overweight or obese koi are more susceptible to a number of health problems, including:

* Liver disease: Excess fat can accumulate in the liver, leading to inflammation and damage.

* Heart disease: Excess fat can also accumulate around the heart, making it difficult for the heart to pump blood effectively.

* Kidney disease: Excess fat can also damage the kidneys, leading to decreased urine output and fluid retention.

* Skin problems: Overweight or obese koi may develop skin problems, such as ulcers and sores.

* Swim bladder problems: Excess fat can also affect the swim bladder, making it difficult for the koi to maintain its balance.

In addition to these health problems, overweight or obese koi may also be less active and have a decreased quality of life.

If you think your koi may be overweight or obese, there are a few things you can do to help it lose weight:

* Reduce the amount of food you are feeding the koi. A good rule of thumb is to feed the koi only what they can eat in 5 minutes.

* Switch to a lower-carbohydrate, lower-fat diet. Look for a food that is high in protein and fiber.

* Increase the amount of exercise the koi is getting. Encourage the koi to swim by playing with it or providing it with toys.

If you are concerned about your koi's weight, talk to your veterinarian. They can help you develop a weight loss plan that is right for your koi.
