Koi Feeding Guide
A Koi's metabolism functions best at temperatures above 70° F. High protein foods are difficult to digest when the water falls below 65° F.
However, Koi still need sufficient carbohydrates for energy when water temperatures are low. This is particularly true for Koi less than 1 year old.
Squash, bread, peas, citrus fruits, and watermelon are good sources of carbohydrates. Never overfeed your fish! Koi do not have a stomach. Feed smaller quantities more frequently for better nutritional absorption.
Feed only as much as the fish will eat in about 3-5 minutes. Koi pellets should be fresh and used within three months to prevent oxidation of the food.
