The Only Koi Food in the World 

Imported to Japan by Top Niigata Breeders

Made in the USA

What's New...

Dainichi Koi FoodDainichi now offers two formulas in Medium Sinking (5 mm) Pellets, for those unfortunate occasions where there are concerns about predation by uninvited pond visitors. Available in the encapsulated ALL-SEASON and PREMIUM formulas only, the sinking pellets may be the perfect solution for the times when a hobbyists' cherished koi catch the eye of these particular "connoisseurs".

What's Available?

We proudly offer two distinct product lines –
DAINICHI FISH FOOD, our original encapsulated line introduced in 1997 and 
INOCHI KOI FOOD, our un-coated line, designed for Japanese breeders and now available to all hobbyists.
The primary difference between the two product lines is the exclusive encapsulation process we utilize to produce the DAINICHI formulas. What distinguishes this food from all others, is that after the extrusion process, we further encapsulate the pellets with additional vitamins, digestive enzymes, prebiotics, garlic and a variety of color enhancing ingredients.

What's Special About our Dainichi Fish Food? 


Dainichi Koi Food

Using our exclusive process, our food is encapsulated with our exclusive vitamin and mineral coating – after the cooking phase. This process ensures heat sensitive ingredients are absorbed into the pellet without being exposed to heat, thereby retaining their potency.

Why is this so important?

Fish nutritionists have proven that the fish's immune system lacks long term memory. The special vitamin and enzyme formula we supplement our food with is essential to boost the fish's immune system response, so your koi can fight off bacterial and viral infections, repair surface damage and increase luster and sheen. All our DAINICHI formulas are coated with a special vitamin and mineral coating after the extrusion process to assure optimum nutritional potency. This cold process ensures that ingredients, which would normally be denatured, or even totally destroyed by exposure to heat, are kept at their full potency. As you may know well know, vitamins and digestive enzymes should not be exposed to heat. However, only DAINICHI KOI FOOD makes this fact a reality. Fully active vitamins and color agents do wonders for your koi's appearance and health. Active digestive enzymes and no fillers promote unmatched digestion rates – that leaves your pond cleaner and healthier. This is especially important in situations where the koi are very large or crowded.

On the other hand, our INOCHI line is produced in the standard production method, where the ingredients are weighed, batched, milled, extruded, dried and finally packaged for sale to the customers. The formulas in this line-up (ALL-SEASON PRO, PREMIUM PRO, COLOR PRO) do not undergo our special encapsulation process. However, they are formulated with the same high quality ingredients used in the DAINICHI formulas.

How good are our ingredients?

Nowadays, virtually every fish food manufacturer or brand brag that they use "premium" quality ingredients. However, with the exception of the white fish meal and the Antarctic krill meal (both of which are actually by-products of fish fillet and krill oil production for human consumption), all of our other ingredients are either organic or human grade.
• NO inferior and deceptive ingredients.
• NO blood or bone meal, feather meal or various glutens used to bump up the protein content on the label.
• NO soy or grain by-products used as cheap fillers meant to pad the profit margins.
The ingredients that go into DAINICHI and INOCHI koi foods are absolutely "top-shelf". Nothing better. We spare no expense in our ingredient selection. Generally, this is not done in the fish food industry, where lower ingredient prices often dictate the quality – first and foremost. The difference is that we are fish lovers too, and will not compromise on the quality of food that bears our name. There are not many "tricks" when it comes to producing the best food...Without the best ingredients, the bragging just becomes a marketing ploy. That is just NOT us.

Finally, with no additional processing required, the uncoated INOCHI foods are cheaper to produce, even though the ingredients and formulations are the same as the encapsulated DAINICHI foods. The performance of the INOCHI foods, with respect to your koi's growth, color and body conformation, live up to professional breeder standards. In fact, we originally formulated these foods for breeders with unlimited water resources and for the use of feeders. The low waste production translates to happy hobbyists – happy at not having to spend their free time on sanitation and maintenance.

What else... makes our foods stand out?



All Dainichi fish foods contain calcium montmorillonite clay. This bentonite clay contains more than 60 mineral compounds and has been proven to be immensely helpful in enhancing digestion and growth, as well as neutralizing metabolic toxins. In an artificial environment such as a fish tank or pond, the clay helps return minerals to the water and stabilizes its chemical make-up. In this way, the water more closely resembles the natural habitat of koi.

In comparison to most food brands, DAINICHI and INOCHI koi foods are higher in protein content. Why? This is due to our use of high protein ingredients like spirulina (52-62%), krill (62%), and pea protein (80%). However, experience has taught us that while too little protein is not enough to maximize the growth and development of koi, too much protein is detrimental to the water quality and thus the general welfare of the koi. Koi simply cannot assimilate excess protein and pass it through in form of waste production. For this reason, most of our foods range between 39 to 42% protein content, and even our most aggressive growth formula (GROWTH PLUS) tops out at 44%.
