When selecting the proper Koi food for your koi the first ingrediant should be fish, followed by fish meal and other fish products. Koi Foods where corn is listed as the first ingrediant may be more economical but tend to make for unhealthy overweight koi.
The nutritional needs of Koi vary throughout the year as should thier Koi Food.During warmer times above 60 degrees koi need more feedings daily. When the temps drop to 56 degrees they require smaller less frequent feedings, and use a cool weather food.
Below 46 degrees feeding should stop.
