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 physique, 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. This is achieved 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, glowing skin.
