Koi Feeding Guide

Never overfeed your fish

A Koi's metabolism functions best at temperatures above 70º F. High protein foods are difficult to digest when the water falls below 65º 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. 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 to 5 minutes. Koi pellets should be fresh and used within three months to prevent oxidation of the food.
