There are many types of koi fish food on the market and we were not satisfied by the options. To meet our family’s high standards of raising beautiful koi, we made our original products available online. Buy our recommended koi food.
It is important to note that because koi enjoy the food, it does not mean that it is the best for their health. Like human food, additives may increase the Koi enjoyment but not the best long-term solution for their beauty and growth.
Growing Beautiful and Healthy Jewels
Unlike other jewels, the beauty of a koi lives and breathes. They are growing beauties and food has a very strong influence on their health and appearance. At Kodama Koi Farm & Gardens, we have spent a lot of time working with Niigata, Japan breeders to maximize the beauty of koi color and increase their longevity. We’ve learned and incorporated many Japanese koi breeding best practices into our farm in order to nurture the most beautiful living jewels (koi fish).
“It is disappointing to see Koi beauty fade and/or health decline. So I decided to share my Koi food in order that other Koi lovers can have the same results and experiences we have had at the farm.” – Mamoru Kodama
In this article, we will share the many important lessons we’ve learned from senior dealers, breeders, customers, and of course, koi, for creating shinier coats, cleaner water, and healthier fish in your pond.
Why Buy Quality Koi Food?
Quality koi food is important not only for fish health but for maintaining excellent water quality as well.
It is important to invest in high-grade koi food because they consist of essential nutrients and vitamins needed to keep koi healthy. In addition to that, they also provide the koi with a steady source of protein, carbohydrates, and minerals.
This causes them to grow bigger and develop more vibrant colors.
High-end koi food also tends to be more palatable so the koi get enthusiastic during feedings. In typical feeding videos, koi tend to swarm towards the surface for the feeding which teaches them to be tamer while enhancing the overall beauty of the pond.
Grand Champion winner, David Tran, stated in an interview that he advocates feeding his koi with premium koi food over the cheaper kind because it:
“may save a few dollars for cheap food but waste a lot of money in koi. It’s like you eating fast food every single meal while expecting to stay healthy and beautiful.”
Champion koi deserve champion koi food. Learn why this food is great for hobbyists and competition koi.
What Do Koi Fish Eat?
Nishikigoi (Koi) tend to eat anything that won’t eat them. They’re omnivorous by nature and have been known to eat algae, plants, animal matter, flies, and bugs in the wild.
However for those who own and grow koi, we tend to have more than just the koi’s survival in mind. The diet needed to keep koi happy, healthy, and beautiful is a science.
Many sources validate the belief that koi need a balanced diet of protein, vitamins, minerals, and carbohydrates to maintain healthy growth.
For protein, most koi are fed wheat germ pellets that integrate the essential nutrients, vitamins, and minerals needed. As for carbohydrates, koi can be fed squash, peas, fruits, and watermelon on top of these pellets.
Why Floating Medicated Koi Food?
NO LONGER FOR SALE – To reduce the overuse of antibiotics and ensure they continue to be effective for humans and animals, the US Food and Drug Administration (FDA) has announced new Veterinary Feed Directives (VFDs) effective starting January 1st, 2017. These regulations authorize the use of medicated foods under the direction of a veterinarian. Antibiotic foods that were previously obtained over-the-counter now require a veterinary order from a licensed veterinarian who has knowledge of the diseases of the fish that he or she is going to treat with the medicated food.
We will soon be releasing information on how to make your own medicated koi food.
Outdated – more info to come soon – Koi that start developing body sores, ulcers, fin rot, and other signs of infection usually mean that there is something wrong the pond. So while figuring out what’s wrong with the pond, it’s best to treat the koi with medicated koi food. Then comes the problem of getting the koi to actually eat it. That is why there is floating medicated koi food.
When koi are sick, they tend to lay on the bottom and not surface to eat. To purposely make them extra hungry, we will occasionally recommend not to feed regular food while feeding medication.
This will make the medicated koi food, with less tasty antibiotics, more attractive while also floating on the surface to lure the koi out of their depths of despair. As mentioned, adding in some sinking food may also be helpful when they do not want to come to the surface to eat.
Floating food will also give the breeder the opportunity to examine the koi’s health when they surface to eat.
When Should I Feed My Koi Fish?
Determine the frequency of feeding by observing the temperature of the water.
Always take measurements and do not base it off the weather forecast or the air temperature. As you will see in this chart, when the water is below 55° F you should be feeding once per week and then subsequently continue with multiple feedings per day. Yellow indicates the water temperature to feed koi.
Overfeeding can also be problematic to the health of your koi and water quality.
- The ideal amount of food will be consumed by the koi within 5-10 minutes.
- Make sure there are no leftovers dissolved in the water. This will pollute water and cause the food to lose its nutritional potency. This is particularly the case with soluble vitamins that quickly dissolve in water.
What Are The Best Types of Koi Food for Growth and Color?
There are many varieties of koi food available and we have tried many of them to our dissatisfaction. Increasing the color and growth of koi is one of the main elusive objectives of champion owners.
Spirulina will enhance the color of your koi as well as improve their immune system. This nutritional supplement enhances the color red and will also make the flesh (skin) of the koi more beautiful.
Wheat germ oil is a major health food in a koi diet. This will help with the overall health of the fish and help it grow to its maximum size. There are many elements that all come together to form a healthy, beautiful, and show-ready koi.
What Are The Ingredients of Kodama Koi Food?
The ingredients to Kodama Koi Food are Wheat Germ, Spirulina, Fishmeal, and Bio Stone.
Wheat germ oil is a widely known health food for humans and the residual, depleted wheat germ is most frequently used in koi food. However, Kodama uses FRESH Wheat Germ with the health-boosting oil still in it. It keeps the koi healthy while improving it’s skin quality.
Kodama also uses quality top quality Spirulina as a nutritional supplement. This floating micro algae is a good source of protein, vitamins, and minerals to help improve immunity and flesh quality of the koi.
This ingredient makes the food more digestible while enhancing the vibrancy of koi colors. Spirulina is mainly used to enhance the red coloring of koi with its natural carotenoid content. Kodama always strives to find Spirulina with high concentrations of carotenoid.
Fish-meal is the main ingredient in many koi foods, as the body and protein of the food. Kodama Koi Food uses only the best fishmeal that is examined for low Histamine and Ethoxyquin levels for less koi health problems down the road.
Bio Stone is a mineral featuring silicon aluminum. It is used in this food because it not only acts to keep koi healthy but also absorbs ammonia in the pond for better water quality.\
Kodama Koi Food also incorporates other complementary vitamins and minerals that meet the high demands of koi nutrition.
How Do I Store Koi Food from Kodama?
When storing koi food, keep it packed in an aluminum bag and it will have a shelf life of three years from manufacturing date. Once the food has been opened, keep the koi foods in a cool and dry place out of direct sunlight. Exposure to high temperatures or sunlight may compromise the nutrition of the ingredients. It is recommended that you repackage your food into smaller portions to feed your koi. Separate it out into daily feed amounts to help you better keep similar feeding patterns. Consistency will reduce stress of fish around feeding time.
