Koi Feeding Guide
A koi's metabolism functions best at temperatures above 70 F. High protein foods are difficult to digest when the water temperature falls below 65 F. However, koi still need sufficient carbohydrates for energy during the winter months when they are not being fed. Squash, bread, peas, citrus fruits and watermelon are good sources of carbohydrates. Never over feed your fish. Feed smaller amounts more frequently for better nutritional absorption. Feed only as much as the fish will eat in 3 to 5 minutes.
