What Do Koi Fish Eat?
Koi are bright, elegant, and majestic fish that descend from the carp. In the past, they were only red, white, black, and blue koi. Since then, koi fish have been bred to reflect combinations of all the colors in the rainbow.
Koi fish are inherently omnivorous. They aren’t picky. They will eat just about anything that won’t eat them. Koi fish have surprisingly a very strong digestive system, so they will eat just about anything manageable you give them.
In the wild, koi fish feed on algae, leaves, plant debris, and even animal feces. If you decide to pet koi fish in an indoor aquarium, obviously you can feed koi on a wide variety of plant- and animal-based foods. Everything you eat normally can be used as a diet for your koi fish as well. So, the koi fish diet could include vegetables, carbohydrate-rich foods, fruits, breadcrumbs, rice, etc.
Koi fish will eat small portions of protein as well. You may want to source proteins from an aquaculture, such as herring meal, shrimp meal, fishmeal, or anchovy. If you want to feed your pet koi multiple times a day, mixing up carbohydrate- and protein-rich meals is a good idea.

The Impact of Food in Koi Fish Color
Since carotenoids are common in many commercial koi foods, koi food affects red koi the most. Sometimes, you will notice white spots on your koi fish turning pink. It could be because you’re giving your fish enough carotenoids. Variety of Vitamins adds to the yellow, red, and orange pigments of your koi fish as well.
Change in koi color takes time. So, don’t expect new food to produce immediate effects. Over the course of weeks and multiple feedings a day, may eventually lead to a change in color.
What Can You Feed to Enhance KOI Color? – Maximize Growth and Color
Just like an adult human being, koi need protein and a little amount of fats to grow well in adult life. On the other hand, various vitamins in koi food will affect the color of your koi’s scales. Choosing the right food for koi makes a huge difference in their growth, color, and health.
There are more than 23 koi fish varieties, most with unique nutritional requirements. Like any other pet, koi fish also need a balanced diet in order to grow and thrive. What many fishkeeping people don’t realize is that koi fish have unique nutritional requirements. You can’t just walk into your local pet store, grab some random can of fish food, and expect it to work for your koi fish.
No, it doesn’t work that way!
Although you’ll come across numerous types of commercial koi food on the market, many don’t contain the right combination of carbohydrates, nutrients, vitamins, and proteins. However, a balanced diet will help your koi fish grow healthy and perfect!
KOI Food Ingredients to Watch Out For
If you’re looking for the best food for your koi fish, the thing you’re likely to look at first is the ingredient label – but what should you be looking for?
The common ingredients that make up koi fish products are plant- and animal-based proteins, Vitamins, minerals, natural and artificial color enhancers, fat percentage, etc. The balanced koi food must have those common ingredients, including a few others. If you want to pick the right koi food, you want to look out for the ingredients below.
Protein & Fats
Similar to humans’ requirements, koi fish also need protein and fats for growth and strength. A lack of these ingredients will keep your koi fish malnourished and week. Regardless of age, koi fish will suffer from a lack of these.
Keep this in mind…
Proteins from aquaculture sources will be much healthier than other lower quality protein sources, such as plant-based proteins. Aquatic protein sources will help your koi fish reach their full potential.
These aquatic protein sources could come from shrimp meal or fishmeal. Additionally, you could buy products that list different aquatic sources for protein supplements. Check out the label on the product whether the first and second ingredient comes from aquatic sources.
Let me tell you more…
The ingredient sources should comprise of the largest proportion of the feeds protein content. There could be minerals, Vitamins coming from secondary sources complementing the primary sources. Animal-based proteins contain essential amino acids, necessary for optimal growth.
What you should remember…
…on the other hand, is plant-based proteins do not offer such essentials. Feeding your koi fish on aquatic protein sources isn’t enough. You have to take note of the percentage of protein content.
Hmm, really vital!
The percentage of protein also contributes to the price of a product and overall growth.
Expert aquarists recommend 30-40% protein content percentage in your koi fish for optimal growth.
Increasing the amount of protein content in koi fish diet doesn’t necessarily contribute to faster growth, rather koi fish will struggle to digest a large amount of protein content, thereby leading to waste. High protein content comes with a price. You don’t want to spend more money on protein content when much of it isn’t even consumed by your koi fish.
Plant Proteins are much cheaper to mix in feeds, compared with animal-based proteins. A feed could contain both plant-, and animal-based proteins. For example, a koi fish feed containing fish meal (1st ingredient) and wheat germ (2nd ingredient) isn’t a low quality combination.
It’s because the fish meal will deliver the bulk of protein to your koi fish. In addition, wheat germ will deliver secondary energy and protein. Containing both the ingredients, the koi feed will be an effective supplement for koi fish.
Vitamins, Minerals, & Immune Boosters
A good koi feed will contain vitamins and minerals in balanced proportions. A koi’s diet containing a wide range of vitamins will improve eyesight, overall growth, skin, digestion, and color.
The vitamin you need to look out for in a koi’s diet is Vitamin C. Vitamin C or Ascorbic Acid combats viral and bacterial infections, so it’s one of the effective ways to boost your koi fish’s immune system naturally. This vitamin further contributes to the development of collagen and cartilage.
In addition to Vitamin C, Vitamin A, B, and K also aid in the development of eyesight, metabolism, healthy scales, blood regulation, and tissue.
Natural & Synthetic Color Enhancers
Many koi owners raise koi because they find colors of koi so vibrant and impressive. Whatever the reason may be, the colors of koi fish are truly amazing to look at.
By the way, you can enhance the colors of your koi fish if you want. Color enhancers can be natural and synthetic, with synthetic enhancers being cheaper and more prominent. Conversely, natural enhancers can be expensive and less potent, compared with synthetic options.
