Complete food with the correct protein-fat ratio of 3:1 according to the NEO Index, which takes water temperature, function, animal size and age into account With wheat, salmon, shrimp, spinach and spirulina for strong and healthy pond fish (at 10-25 °C water temperature) Food sticks in a resealable, airtight, waterproof and lightproof bag to maintain quality NEO Index literally means: Natural energy-optimized nutrition.
