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
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.
Water Temp. (°F.)
Less than 50ºF.
Do not feed Koi.
Temperatures at 50° F. of more than one month may require supplemental feedings of low protein and high carbohydrates.
2-3 times a week if Koi are hungry.
High carbohydrate, low protein, laxative type foods.
Wheat germ, Cheerios®, squash, lettuce and brown bread.
4-5 times per week if Koi are hungry.
Add low protein (25%) pellets along with vegetables. Increase quantities gradually as temperature increases.
Once per day six days per week.
Low protein (25%) pellets along with high carbohydrate vegetables
Once per day every day.
Gradually increase protein in
pellets (35%) and quantity of pellets. Vary diet with vegetables and fruit.
Once or twice per day.
Bulk of diet should be 35% protein pellets. Add fruits, vegetables, and plankton for variety.
3 to 4
times per day.
High protein pellets (35% to 40%) with color enhancers. Add plankton, vegetables, fruits, and
