Koi Fish Diet

When it comes to koi fish the wild, they are omnivores and will eat pretty much anything that they can fit in their mouths. As long as it doesn’t eat them, and they can manage to fit it into their gullets, chances are that they will eat it. In the wild, koi fish will eat things like insects, insect larvae, little fish, algae, dead animal matter, plants of all sorts, and any kinds of veggies and fruits that they can get their mouths on.

Strictly speaking, koi fish do need a fairly balanced diet to meet their nutritional needs. Yes, they need to consume a fair amount of protein, but they also need vitamins, minerals, and carbohydrates as well. In other words, they can’t eat just one type of food to be healthy and happy. They need a balanced diet that includes all of those proteins and other essential nutrients.

There are lots of different food choices to go with, but the best is a balance between various options. Of course, the selection of food in the wild where koi live is going to be a little different from what you can feed them at home, but none the less, you still have the ability to provide them with a balanced diet if you pick the right foods.

When Should I Feed My Koi Fish?

Now, we probably all know that overfeeding a fish of any kind is not good at all. Overfeeding a fish can and does result in numerous health issues that should be avoided at all costs. You can’t go feeding these fish as much as you want and expect them to be fine.

Now, what is interesting to note is that feeding koi fish, especially those in outdoor ponds, is a little different than feeding indoor aquarium fish, at least in terms of the amount and schedule.

First, you need to make sure that you don’t feed the koi carp more than they can eat in about 7.5 minutes. This does depend on the size of the specific fish in question. A smaller koi should be fed for about 6 minutes, while larger ones may be handle anything up to 10 minutes.

Moreover, when and how often you feed your koi will depend on the temperature of the water. The warmer the water is, the faster the koi’s metabolism is, the more you need to feed it.

Let’s take a quick look at this koi feeding chart that illustrates how often a koi needs to be fed based on the temperature of the water which they are living in. Just so there is no confusion, we have used Fahrenheit as the temperature reading.

Water Temp Feedings Per Day
50 to 55 Once per week
55 to 61 Once per day
61 to 65 Twice per day
65 to 73 Three times per day
73 to 77 Four times per day
77+ Five times per day

What Can I Feed My Koi Besides Fish Food

One of the things that we want to get out of the way right away has to do with feeding koi fish Cheerios. People have been asking us whether it is Ok to feed these guys Cheerios.

Ok, so technically speaking, yes, a few cheerios here and there won’t hurt your koi. However, Cheerios are not as nutritionally complete as real fish food, so you can’t use them as a meal supplement.

They can only be used as occasional snacks, and only a few at a time. This is like asking whether or not it is OK for humans to eat chocolate. The answer is no, not really, but a little bit every now and again won’t kill you.

That being said, there are plenty of things besides fish food that you can feed to your koi. What are some of the best things to feed your koi besides fish food?

  • Bread – with or without honey.
  • Prawns.
  • Shrimp.
  • Shelled crab.
  • Daphnia.
  • Feeder fish – such as small goldfish.
  • Cockles.
  • Worms of all sorts.
  • Sweet corn.
  • Oranges.
  • Lettuce.
  • Spinach.
  • Cucumber.
  • Zucchini.
  • Other leafy greens.

How Long Can Koi Fish Go Without Food

You might not always be home, you might forget an occasional feeding, or you might be out of town for a couple of days. Don’t worry though, because koi carp can go for a good few days without being fed. While they might be hungry after 3 or 4 days without you feeding them, they won’t starve.

However, by day 5, make sure to give them a good meal. Of course, they will probably be hungry by this time, but they won’t die.

They might even be able to survive for longer depending on the biological diversity in the pond which they live. If there is tons of algae, some small fish, and other plant matter, plus insects in the pond, they can forage for food.

While they can’t necessarily survive for more than 4 or 5 days without food of any sort, they can look for it themselves in the pond. In other words, if you miss a feeding here and there, it is no big deal, but still, try not to do this very often.

Commonly Asked Questions

What are the best koi food brands?

If you are looking for some really high quality koi fish food, stuff that will provide your koi with all of the nutrients they require to meet their dietary needs, to help enhance their color, and to keep them healthy, there are some trusted brand names that are very popular.

These include the following.

  • Shinju.
  • Hikari.
  • Dainichi.
  • TetraPond.
  • Kaytee Koi’s.

How can I make my koi grow faster?

One of the best ways to ensure that your koi fish’s growth rate is as fast as can be is to maintain the ideal water temperature in the tank or pond.

Now, it is not like koi fish cannot handle cool water, but it is not best for fast growth. If you want to ensure a fast growth rate, you should keep the water in the koi pond between 77 and 80 degrees Fahrenheit.

Moreover, ensuring that you provide your koi fish with the proper diet and more than enough food will also help increase growth rates.

How can I enhance my koi fish color?

You can naturally enhance the color of your koi fish by providing it with the proper nutrients. There are various specialized color enhancing koi fish foods out there.

What you want to look for are tow main ingredients that are well known for helping with this. These ingredients are Spirulina and carotene.

Yes, here we are talking about carotene, that stuff found in carrots which gives them their orange color. This will give your koi fish their orange color too.

Now, if you want to make your koi look more colorful, also try to make it so that the colors in the pond, the water and plants, contrast with the koi, to make the fish really stand out.

How much should I feed koi?

Koi fish should be fed just once per day, and they should be fed as much as they can eat in about 5 minutes.

Keep in mind that the amount of food which a koi needs will depend on the time of year and temperature, but once per day and 5 minutes is the general rule of thumb here.

Why are my koi always hungry?

Well, your koi fish are probably always hungry because your are not feeding them enough. If feeding them once per day for 5 minutes is not enough, try increasing this to 6 minutes.

You can also try spreading out their feedings to twice a day, to 2.5 or 3 minutes apiece. The other reason why koi fish are always hungry is because they don’t actually have stomachs, so they cannot store food for digestions.

Whatever they eat passes right through them, more or less, so they always feel hungry. However, this does not mean that you should constantly feed your koi, as whatever you do give them will still provide them with the required nutrients.

Can koi die from overfeeding?

Yes, overfeeding your koi fish can be quite dangerous and in some cases may lead to death. So, what can happen if you overfeed your koi fish?

  • Increased biological waste in the pond.
  • Decline in water quality.
  • Lowered oxygen content.
  • Damage to kidney and internal organs.
  • Increased chance for disease onset.
  • Fin rot.
  • Death.


As you can see, there are many options to go with which in your mind might qualify as the best food for koi carp. We would of course recommend the number one choice that we picked, but any of the others are just fine too.

Remember to feed your koi carp a good and well balanced diet and make sure to monitor water temperature so you know when and how often to feed them.
