It is no secret among koi breeders that the food quality has a major impact on the fishes’ health and colour vibrancy. Tetra KOI beauty contains betacarotene which helps koi to achieve full colouration and makes them eye-catching in the pond. Food is made up of various basic elements, proteins, fats, carbohydrates, vitamins and minerals. A balanced combination of these elements is not only essential for humans, but also for koi. Like most cyprinids, koi are omnivorous. This means that they need animal as well as vegetable components in their food.
