Koi will eat both animal and vegetable matter which makes them omnivorous. They do not have stomachs so they can not eat a large amount of food at one time. This is the reason Koi spend a great deal of time foraging around for Koi food. They will actually eat just about anything that is small enough for them to swallow whole.
The hand- feeding process can be pleasurable for both you and your Koi. Instead of throwing the Koi food into the pond, take the time to place the Koi food into the water at the same area daily.
In so doing, the Koi will become accustomed to the routine and will, over time, become friendly and trusting enough to be hand- fed. Koi have even been known to recognize there owners' footsteps and follow them around the waters edge.
Taming and training your Koi is a gradual process, but it can be very rewarding. Spending this time with your Koi will also allow you to observe any problems early on.
Quality Koi Food Many Koi owners do not realize the importance of feeding. Not only must consideration be given to the amount and time of feeding, but to the combinations of foods that are essential for healthy and colorful Koi.
Koi food can be divided into proteins, fats, carbohydrates, vitamins and minerals
Feeding fish versus Temperature:
Less than 50°F Do Not Feed
50°F-60°F 2 -4 times weekly
60°F-85°F 2-4 times daily
Above 85°F Do Not Feed
In all cases, try to feed only what the fish will normally consume in about 10 minutes. Remove any uneaten food within an hour.
