What Do Koi Fish Eat? 

Koi fish are omnivores that have a strong digestive system. As long as you offer them natural items that they can swallow, they will consume pretty much any type of food you feed them.

Koi fish eat algae, insects that land on the water's surface, leaves and other plant detritus, and even animal feces in the wild. You may provide a wide range of foods to Koi while they are in captivity. They'll eat fruits and vegetables, as well as carbohydrate-rich meals like bread, rice, and cereal. They'll even consume tiny protein sources like shrimp or shredded chicken chunks.

Benefits of Making Your Own Koi Fish Food

  • You can customize the diet to fit the specific needs of your fish.
  • It is less expensive than commercial koi foods. Even further savings may be made by utilizing your own food waste, such as fruit and vegetable peels, that you would normally throw away or compost.

  • It's organic, which implies it has more nutrients than processed meals. Fresh ingredients are used rather than manufactured food that has been sitting on a shelf or in a box for a long time

  • You have control over the quality of the ingredients that go into your koi fish food. This is especially important if you want to ensure that your fish are getting a balanced diet.

Nutritious Ingredients for Koi Fish

Essential Nutritious Ingredients for Koi Fish 

When deciding which components to add to your own fish food, remember the nutritional requirements of koi. Your koi's diet should be about 35% to 40 percent protein content and supplemented with fruits and vegetables for additional important vitamins, carbohydrates, and lipids. Peas, squash, spinach, citrus fruits, broccoli greens, raspberries, and watermelon are some good options.

Carbohydrate Sources 

Carbohydrate sources are an excellent method to add fiber, protein, and vitamins, as well as minerals, to your koi's diet. Protein content intake should decline as the season progresses and temperatures drop, while carb consumption should rise to give much-needed fast energy in the winter.

Some of the carbohydrate foods include oat bran, wheat germ, bread, Cheerios, and other dry cereals. Fruit is a good carbohydrate source. To avoid liver damage, keep your koi's diet low in carbohydrates (less than 10%). Cheerios and other starchy foods are to be avoided as staples since they're extremely starch-rich.

Protein Content Sources

Koi are adapted to readily digest plant-based proteins and can be fed alongside natural animal protein content, like bloodworms and shrimp, for a complete supply of vitamins, minerals, and amino acids. Soybeans, spirulina, and wheat germ are all excellent plant-based protein sources for koi; shrimp, krill, and insects are examples of preferred animal-based proteins that may be purchased fresh, frozen, or freeze-dried. They are all high in Omega-3 fatty acids, making them a good choice for keeping your koi healthy and shiny.

Fats, Vitamins, and Mineral

Lipids (or fat content) have double the energy of protein or carbohydrates, as well as essential fatty acids that help promote healthy growth, prevent deformities and skin problems, and support good pigmentation.

Fat content should make up approximately 5 to 10% of your koi's diet and can be found in linseed oil (flaxseed) or fish oil, although linseed oil is preferable since it includes all of the essential fatty acids required by koi - linolenic acid and linoleic acid.

If you want to keep your koi in an outdoor pond, increase the number of lipids by a few percent as you approach fall and winter. Koi also require different vitamins and minerals, including vitamins B, C, A, D, and K as well as iron, copper, magnesium, and other nutrients. These nutrients can only be obtained via eating food because they are not absorbed from the water like other minerals.

Things to Avoid 

Koi are voracious eaters. They'll eat just about anything they can get their mouths on, including fruits and vegetables. However, there are a few foods to avoid while offering your koi since they may have harmful consequences on their health.

Do not feed them:

  • Processed foods like hot dogs, hamburgers, or chips
  • Dairy products like milk, cheese, or ice cream
  • Loaves of bread or cereals
  • Fatty foods like french fries, bacon, or fried chicken
  • Spoiled or rancid foods like fish heads, rotten fruit, or old vegetables
  • Algae tablets or wafers

These are all unhealthy for koi and can cause problems such as swim bladder issues, poor skin quality, and digestion problems. It is best to stick to a balanced diet of homemade koi foods, pellets, fresh or frozen food, and a sample size of live food. This will provide them with all the nutrients they need to stay healthy and happy!

Koi Feeding Tips

Feed your fish four times a day, if possible. Only offer them as much as they can consume in about five minutes.

  • Avoid feeding your koi fish before storms. Fish need more oxygen when digesting food. When it rains, oxygen levels in the air dip down, so you can see why it's a bad koi fish feeding time.
  • Your little koi fish will need to eat koi flake food or tiny koi food. Larger koi fish prefer pebble food. This will help them grow to their potential.
  • Your koi fish prefer more carbohydrate-rich foods early in the spring and late in the fall while protein is better in early summer when mating is in the air (er, pond).
  • Koi fish can go all winter without eating because their metabolism slows to a crawl. Therefore, make sure the little food they eat contains enough nutrition to sustain their health.
  • The amount of food you put in the water will determine how fast it decomposes and fouls the water. So, don't overdo it!
  • When introducing new food to your fish, do so gradually over a period of seven to ten days, mixing the old and new foods together. This will minimize the chances of your fish developing any digestive problems.
  • Don't feed your fish during winter if their water temperature dips below 50 degrees Fahrenheit because it can cause health problems.
  • Koi fish feeding is not recommended if your pump breaks because your koi need oxygen to digest their food.

FAQ

How Do You Make Koi Food for Fast Growth? 

A large, warm habitat and a high-quality diet might help your koi develop more quickly.

How Does Food Affect Koi Fish Color?

Vitamins in the diet influence the pigments on Koi scales, which then have an impact on your fish's hue. Vitamins A, C, and E are essential for the color of your Koi fish.

Choosing the appropriate food for your Koi is an important part of optimizing their health, development, and color.

What Are the Factors That Affect Koi Feeding? 

There are a variety of reasons why you should feed your Koi, including their age, body size, and season. These fish are always developing and their nutritional needs vary based on the water and weather conditions.

  • Size Of the Fish

Most fish will do well with tiny sinking pellets that are 3/32" in diameter or less, as a general guideline. Larger fish, such as those longer than four inches, will have more favorable eating habits if they eat floating pellets with a diameter of 3/16 inches. You should use pellets with a diameter of ¼” or greater if you’re Koi are 8 to 10 inches long or longer.
  • Season matters
    The amount of carbohydrates versus proteins your Koi require in their diet varies with the temperature of your Koi pond. In the winter, when the water is cold, your Koi will need a diet that is high in carbohydrates and low in proteins. In the summer, when the water is warm, your Koi will need a diet that has more protein and fewer carbohydrates. In the fall and spring, when temperatures are moderate or fluctuating, offer your Koi a combination of carbohydrates and proteins.
  • Water Temperature
    The temperature of the water in your Koi pond also impacts their eating habits. When the water temperature is colder than about 50 degrees Fahrenheit, carbohydrate-rich diets are advised. Protein-rich foods are preferable when the temperature is greater than 70 degrees Fahrenheit. You can mix carbohydrates and proteins to suit the needs of your Koi at temperatures in between.
  • Age of the Fish
    When your Koi are young, they will need a diet that is high in proteins, vitamins, and minerals. As they grow older, the diet of your pond fish should become more balanced with a focus on quality over quantity.
