Koi are omnivorous fish that eat just about anything that won’t eat them. Koi fish can thrive on aquatic insects, animal matter, and even algae at the bottom of your pond. However, you’ll want to make sure your koi gets the right nutrition to stay healthy. After all, part of the appeal of raising koi fish is getting to feed them by hand, where you can admire their size and beauty as they swim near the surface. So, you must be wondering, what is the best koi food?

The best koi feed is rich in essential vitamins and minerals that promote growth and enhance beauty. Koi food rich in protein helps your fish grow stronger and larger, while koi food rich in spirulina enhances koi pattern colors. This article discusses the factors that contribute to a koi fish’s growth and beauty and includes some koi food brands that offer the essential nutrients you are looking for.

Best Food to Feed Koi Fish

Since you want your koi fish to grow big and beautiful, you need to pay close attention to the kind of food you give them. On top of having nutritional value to your fish, high-quality koi food can help keep your pond clean.

Koi food that is easily digestible creates less waste in the pond, which means your pond water will be less cloudy. With clear pond water, you won’t have to spend too much time cleaning the entire pond yourself. Plus, you won’t have to worry about your koi getting sick because of poor water conditions.

Here are some of the best brands that pond breeders agree on

Koi Food For Growth

TetraPond Koi Growth Food is a popular brand for promoting koi growth. This fish feed provides a high-protein diet, ideal for koi fish to grow larger. Koi fish digest protein-rich foods into amino acids, which make up healthy tissues for healthy growth. Lipids are other nutrients that contribute to koi fish’s growth.

Lipids and carbohydrates are sources of energy. Koi are active fish that swim vertically more than they do horizontally. They need all the strength they can get to swim up and down your home pond for you to admire.

Finally, vitamins are necessary to maintain a healthy immune system and proper metabolic reactions. Meanwhile, minerals like calcium and magnesium help develop your koi’s bone structure to make sure they grow big.

Koi Food For Beauty

Shinju White Pearl Enhancer Wheat Germ is one of the best koi fish feeds to enhance beauty. This brand has color enhancers in its formula, meaning developers created this koi food intending to make koi colors more vibrant.

This koi food contains spirulina, an ingredient that contributes to your koi fish’s red and orange colors. Spirulina contains β-carotene, cryptoxanthin, and zeaxanthin, which are common carotenoids, or natural pigments that enhance reds and oranges. These are the same pigments that give salmon, lobster, and shrimp their colors.

Other brands like Blue Ridge Fish Food Pellets contain marigold extract in its formula. Marigold extract helps enhance your koi’s yellow colors. This brand claims to improve color vibrance in only 30 days of feeding this koi food.

Koi Feeding Time

Koi Feeding Time

In terms of weather or season, the best time to feed koi fish is when water temperatures are at least 86°F (30°C). Koi fish are most active when water temperatures are between 68°F (20°C) and 86°F (30°C), meaning you might have to feed them up to four times a day.

When water temperatures drop below 68°F (20°C), koi fish digestive systems slow down. By this time, you should only feed your koi once or twice a day. Any temperature lower than this may leave you wondering why koi will stop eating. They’re most likely hibernating by then.

In terms of the time of day, the best time to feed koi fish is during midday when the pond is warm. When water temperatures are warm, koi have a high metabolism. Typically, you would only feed koi once a day.

You want to feed your koi fish only as much as they can finish in five minutes. If you notice any uneaten koi food after five minutes, try feeding them less next time. You want to avoid overfeeding your koi.

Overfed koi will resemble tadpoles in shape, where they have wispy tails and large upper bodies. You want your koi to grow beautiful, and this tadpole shape may not be the most beautiful shape for koi.

Besides overfeeding koi, you risk pond contamination with too much uneaten food in your pond. Your pond may turn cloudy from the uneaten food, which may lead to further complications among your fish and the entire pond.

Your pond’s quality will affect your koi’s eating habits. Poor water quality boosts chances for your koi to get sick or injured. Sick koi fish are less interested in food, which could worsen their condition and develop more illnesses.

Should your koi get sick, quarantine the affected fish in a holding tank until they recover. In the meantime, be sure to conduct maintenance measures and clean up your pond.


Great quality koi food is rich in vitamins and minerals that promote growth and beauty. Koi are popular pond fish because they grow large and have vibrant colors. Their diet should contribute to enhancing these qualities.

Koi food rich in protein contributes to koi fish’s growth. Meanwhile, spirulina-rich koi food improves koi color vibrance. Some of the most popular fish food brands among breeders are TetraPond, Shinju, and Blue Ridge. These brands provide the necessary nutrients for ideal growth and beauty enhancement in koi fish.
