What do koi eat?

Koi are omnivores. This means they will eat everything, including worms, insect larvae, small fish, eggs, algae, and plant debris.

Like wild carp, koi are constantly feeding on the bottom, searching for food by taste, touch and smell. You will often see them sucking algae and other floating food from the surface of the water. Koi will also scrape algae and bacteria off the surface of plants and rocks.

However, when living in a backyard pond, nature can’t always provide the koi with the food they need. That’s where commercial fish food comes in. Fish food manufacturers develop special diets only for koi in artificial ponds.

Sinking or floating pellets?

The sinking pellet lands right at the bottom of the pond. Koi will feed along the bottom of the pond, easily detecting the smell and flavor of the pellet.

Since koi’s mouths are designed for bottom feeding, it’s natural for them to feed on sinking pellets. But koi are smart and like to rise to the surface to eat.

Floating pellets allow you to see the fish float to the surface. Large fish will rise out of the water looking for floating pellets. They will feed from your hand. You will also find floating stick food.

Koi will grind up the sticks as they chew and swallow. The floating pellets make it easy to see the amount of food being added to the pond. Skilled koi keepers can measure the sinking food. That way, they won’t over eat. You can feed two types of pellets at the same time.

Other Koi feeding tips

Want your koi fish to live a long, happy and healthy life? Then, take note of these tips and suggestions.

  • From insects and bugs to algae and plants, Koi can eat almost anything. They even like people food like watermelon, peas, rice, shrimp, lettuce and grains.
  • Don’t feed them before a storm hits. Koi need more oxygen to digest their food. Also, when it rains, the oxygen level in the air drops.
  • Avoid feeding koi if your aquarium pump is broken. Keep in mind that these fish need some oxygen to digest their food.
  • Koi prefer carbohydrate-rich foods in late fall and early spring. Also, foods high in protein are best during the ideal mating season in early summer.
  • Larger Koi prefer a pebble diet, while smaller Koi will need to eat small fish or fish fillets.
  • Feed them consistently and soon they will recognize you and even greet you as they approach the pond or aquarium.
  • Finally, koi feeding is enjoyable, relaxing, and even therapeutic. So, enjoy your precious time with your beloved fish.

How to Choose Koi Food – Buying Guide

Still can’t make a decision? Here are a few things to consider when looking for the best fish food for your koi.

The quality of the koi food

Sadly, there are many local pet stores today that sell junk brand foods that are labeled and identified as koi food. In fact, some of these recipes and mixtures are made for other fish and are simply labeled as koi food.

While most of these options are affordable, they come with many drawbacks. For example, these koi foods contain incorrect proportions of vitamins, are malnourished, and contain fillers that can damage or even kill the fish.

Therefore, stick to trusted brands. Also, don’t forget to read reviews about the best koi foods.

The Season

Not every koi food is suitable for all seasons. In winter, when the pond water is cold, koi need low protein and high carbohydrate levels, especially as these fish are very active, which means they are hungry.

Koi food with malt is ideal for winter.

In the summer, when their water temperature is very high, these fish slow down and need higher protein levels for optimal growth and maintenance of their bodies. You should choose koi foods that use krill or spirulina as a protein source.

Mix koi fish with protein and carbohydrate-rich fish foods in the spring and fall, when temperatures change or are moderate.

Koi food content and ingredients

The content and composition of koi food is vital to the growth and health of the fish. When looking for the best koi food, be sure to check these important sources.

  • Protein sources and percentages: for optimal growth, look for koi foods with a protein percentage of 30 to 40 percent. Also, look for healthy protein sources such as herring meal, anchovy, shrimp meal, fishmeal, wheat and soy.
  • Immune boosters, minerals and vitamins: Fish foods that contain multivitamins will help promote a more vibrant complexion, growth, digestion, vision and healthy skin.
  • Color Enhancers: Shrimp or krill oil and spirulina are the most common and popular natural enhancers.
  • Fat percentage: If your koi is small and still growing, you should choose a food with a higher fat content.
