Fish Foods for Koi and Goldfish

Fish Foods for Koi and Goldfish

Feeding your koi or goldfish is one of the most enjoyable times you will spend with your pond. It provides the oportunity to bond with, tame and train your fish.

Always place the koi food in the same place each time you feed you fish. This way the fish learn that when you are in this spot, it means they will be fed. Soon you can train them to eat out of your hand.

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.

Because fish are natural foragers, we recommend several small feedings per day, rather than one larger one.

Only feed enough for the fish to consume within about five minutes. When switching foods, feed a mixture of old and new foods for several days to allow the fish to become accustomed to the new diet.

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.
