Growth — the koi growth food for maximum size
Nijikawa Growth is a 45% protein koi growth food built on a complete amino-acid matrix. It puts on real size and true body conformation — not just bulk — during the warm-water growth window. Floating pellet, prime-grade NON-GMO ingredients, 5mm and 7mm.
45% protein, built for growth
The highest-protein formula Nijikawa makes. A balanced amino-acid profile turns that protein into real muscle and body shape in young, growing koi.
Conformation, not just size
Induces collagen synthesis for better skin quality and the volume and shape judges look for.
Protects water
Highly digestible, durable floating pellets hold together through heavy growth feeding and keep water cleaner.
NON-GMO
Prime-grade ingredients, very palatable and easy to digest.

How to feed for growth
Feed Growth as the main food through the warm-water growth window — roughly 68–77°F — in 2–4 small meals a day your koi finish in minutes. Growth feeding means more waste, so keep filtration and aeration ahead of it. Ease off as the water cools, and switch to a sinking koi food if your fish hold deep or feed shyly at the surface.

Choosing the best koi food for growth
Growth food earns its place in one season: the warm months when koi actually put on size. That is what Growth is formulated for — 45% protein and 10% fat, the highest protein of the four Nijikawa formulas, fed heavily while the water is warm. Use Color Genesis when finishing color is the priority, Four Seasons as a lower-protein staple through spring and fall, and Professional when you need the same rich nutrition in a sinking pellet.
