KiGen TOSAI premium KoiFood.

Refined nutrition for the healthy, harmonious development of tosai.

Tosai is a high-quality growth feed specially developed for the intensive and controlled rearing of young koi from approximately 12 cm. This premium formula supports not only rapid growth, but above all a harmonious body shape, strong bone structure, and refined skin quality—exactly what serious koi hobbyists strive for.

The increased protein and mineral levels, combined with a perfectly balanced protein/fat ratio, optimally meet the increased nutritional needs of growing koi. Without unnecessary strain on the metabolism or the filter system. Unique functional additives such as antioxidants, active clay, and natural herbal oils contribute to excellent vitality, stable digestion, and a powerful immune system. The high proportion of spirulina and astaxanthin stimulates deep, natural color development and supports clear, shiny skin.

The addition of Enzym+ optimizes phosphorus absorption and strengthens the skeletal structure, contributing to even growth and acting preventively against growth-related abnormalities.

Tosai is the ideal choice for hobbyists and professionals. Make no compromises and strive for maximum quality, health, and aesthetics in every growth phase of your koi.
