A professional use daily diet for koi which promotes development of a healthy, voluminous body. We recommend Saki-Hikari Balance as a daily diet for all championship grade koi or koi with championship potential.

  • The nutrient balance offers a readily accepted taste most koi love.
  • Significantly improved feed efficiency offers active waste reduction. This can translate to improved pond bio-action effectiveness which normally means less filter maintenance and improved water quality.
  • Supports digestive system health which can translate to improved nutrient utilization and more rapid growth.
  • Expect predictable growth, superior form, brilliant luster and no negative impact to the Shiroji (white areas).
  • Helps improve energy reserves thereby positively impacting activity levels and development.
  • Most effective when used without interruption as an exclusive daily diet. The benefits of the Hikari-Germ do not continue once feeding is discontinued. Intermittent feeding or use with other foods mixed in will not provide the optimal benefits.

Feeding suggestions: Carefully feed the amount your fish will completely consume within a few minutes, based on your water temperature, pond condition and the activity level of your fish.

Formulated with an extreme focus on growth. this formula is highly enriched with easily assimilated marine proteins. Growth Plus promotes a rapid rate of growth while ensuring optimum body conformation. This formula yields best results when fed during the warmer months when koi are the most active. Like all Dainichi foods, Growth Plus contains calcium montmorillonite clay to simulate the natural ingestion of mineral particles and to bind and neutralize metabolic toxins. 

Raw, fully potent vitamins in the encapsulated coating and the digestive enzymes and garlic ensure that the fish are healthy and free of internal parasites. With only two sources of starch (flour as binder and wheat germ as a source of vitamins E and B), Growth Plus keeps the body conformation of all koi in a constant show-ready condition.

A three-way mix of our most popular koi foods, APG Mix eliminates any decision-making processes. Equal parts of staple, growth an show formulas, APG offers a convenient sample of the All-Season, Growth Plus and Premium koi foods, enabling koi keepers to satisfy the absolute widest array of their prized koi's needs.

ALL-SEASON is an excellent year-round source of easily assimilated marine and vegetable proteins, as well as vitamins C and E. Spirulina and shrimp meal give this formula both mild color enhancing property and a moderately high protein content, making it especially great for colder weather when koi's metabolism is less active. As with all other Dainichi koi foods, the addition of calcium montmorillonite clay and un-cooked digestive enzymes give ALL-SEASON an unmatched digestion rate. Enhanced with vitamins and minerals essential to healing skin blemishes and abrasions, ALL-SEASON will maintain your koi in their top form.

PREMIUM is an overall color, growth, and maintenance food. It can be used alone or in conjunction with other more specialized formulas like GROWTH PLUS or PRIMARY. PREMIUM combines a perfect balance of color and growth, and is an ideal food for keeping your koi in show quality condition. Featuring five sources of protein, of which spirulina, krill, and shrimp meal are also color enhancing, this formula is an all-time favorite with serious hobbyists and many top Japanese koi breeders. A two-step application of vitamins and minerals, especially vitamins C & E ensures that luster, sheen and white are at their best. The addition of calcium montmorillonite clay, garlic and fully active, un-cooked digestive enzymes, makes this formula virtually un-beatable in terms of digestion and performance.

GROWTH PLUS contains a unique blend of montmorillonite clay, white fish meal, krill, and shrimp . This formula provides your fish with a high amount of marine protein which promotes both rapid growth and color enrichment. GROWTH PLUS also features an appetite-enhancing nutritional coating containing calcium montmorillonite clay and un-cooked digestive enzymes which facilitate the highest degree of digestibility. Growth Plus will not foul the filter or water. It is suggested for use during the warmer or high growth months.

Usage: In temperatures of 60°F and above, feed fish as much as they will eat in 5-10 minutes, 2 or more times daily.

This floating food must have 70-80% floating to pass inspection. This is not a bad thing because there are always fish in the pond that can't compete with the others and will benefit from the pellets that sink.

Please Note: New to this season you will notice that this food is now one consistent pellet as opposed to 4 distinct pellets. Microbe-Lift made the investment to reformulate the Variety mix to include ALL the nutritional benefits of the formulas of our Summer Staple, Fruits and Greens, Immuno Food, and Growth and Energy into one pellet. The greatest benefit is that it now ensures that every bite of food the fish ingest has the benefits of 4 varieties. An additional improvement is that now the food can be easily used with automatic fish feeders when needed.

With Added Color Enhancers

In the late spring when the warmer temperatures arrive, koi and goldfish need a boost of protein for growth since they depleted their fat reserves over the winter. In the fall a higher protein diet is also required since pond fish need to bulk up in preparation for their winter fast. Use this feed at a minimum temperature of 68°F (20°C). Pond fish really start to grow at this temperature. You can use this feed up to four times per day. Feed between 2% - 3% of the fishes' body weight per day.

Growth Koi Food Quick Guide

Growth koi food is made for warm-water feeding when koi are active and can use higher protein levels for size, body development, and conditioning. For most ponds, growth food is a seasonal food rather than the only food used all year.

Best everyday start

Start with Hikari Hi-Growth when your pond is warm and koi are feeding aggressively.

Premium conditioning

Choose Saki-Hikari Growth or Nijikawa Growth for higher-end growth feeding.

Bulk value feeding

Use Blue Ridge Growth Fish Food when feeding larger ponds or multiple koi.

Cool water alternative

In cooler spring or fall water, move to wheat germ food instead of high-protein growth food.

When to Use Growth Koi Food

Growth food performs best when koi are active, water is warm, and the pond has strong filtration and oxygen. If water temperature drops or fish activity slows, switch back to staple or wheat germ food.

Water temperature Best food direction Feeding note
Below 50°F Do not feed if fish are inactive Only feed when fish are active and the product label allows it.
50–60°F Wheat germ food Feed lightly because digestion is slower in cool water.
60–68°F Staple food or light growth feeding Use growth food only if fish are very active and water quality is stable.
68–70°F+ Growth koi food This is the best range for higher-protein growth diets.

Popular Growth Food Types

Different growth foods fit different ponds. Some are designed as everyday warm-season foods, while others are better for premium conditioning, larger koi, or bulk feeding.

Food type Good fit Shop
Everyday growth food Good first choice for most warm-water ponds with active koi. Hikari Hi-Growth
Premium growth conditioning Best for koi keepers focused on growth, body shape, and higher-end conditioning. Saki-Hikari Growth
Bulk growth food Useful for larger ponds, repeat feeding, or better cost per pound. Blue Ridge Growth
Growth and color support Good when you want warm-season growth support plus color-focused feeding. Sakana Growth & Color
Sinking growth food Helpful when floating food is not ideal or when fish prefer feeding lower in the water. Saki-Hikari Growth Sinking

Choosing the Right Pellet Size

Match pellet size to the smallest fish you expect to feed. Pellets that are too large can cause waste, while pellets that are too small may be eaten too quickly by larger koi.

Fish size Best pellet direction Why it matters
Small or young koi Small pellets Easier to eat and helps reduce uneaten food.
Medium koi Medium pellets Good everyday size for many mixed backyard ponds.
Large koi Medium or large pellets Larger koi can handle bigger pellets, but medium pellets still work well in mixed ponds.
Mixed-size ponds Small or medium pellets Choose a size that smaller fish can safely eat so feeding competition is reduced.

Growth Food Feeding Tips

  • Use growth food when water is warm and koi are active, not during cold-water feeding periods.
  • Feed only what fish will eat within a few minutes and remove uneaten food.
  • Increase feeding slowly when switching from staple or wheat germ to growth food.
  • Watch ammonia, nitrite, clarity, and oxygen because growth feeding can increase waste load.
  • Store food sealed, dry, and cool so the food stays fresh between feedings.
  • For cool water, move back to wheat germ koi food.

Growth Koi Food FAQs

Is growth food okay to feed every day?

Growth food can be used as a regular warm-season food when koi are active, water quality is stable, and the product label supports daily feeding. Many pond owners still rotate with staple food depending on season, fish activity, and water conditions.

When should I switch from wheat germ to growth food?

Switch when water is consistently warm and fish are actively feeding. If the pond is still in a cool spring or fall pattern, wheat germ food is usually the safer starting point.

What is the difference between growth food and staple food?

Staple food is a general daily diet for normal feeding. Growth food is usually higher in protein and is intended for warm-water periods when koi can use the added nutrition for body development.

Should I choose floating or sinking growth food?

Floating growth food is easiest for monitoring how much fish eat. Sinking growth food can be useful when fish are shy, when floating food is not ideal, or when you want food to reach lower-feeding fish.

Can growth food hurt water quality?

Any food can hurt water quality if overfed. Growth food can add more waste because fish are often fed more during warm weather. Keep portions controlled, remove uneaten food, and monitor water quality during heavy feeding periods.
