Feeding fish

With large fish such as koi, you can certainly attempt hand feeding. Teach them to associate you with food by feeding them several times as day, remaining by the pond. Do not make any sudden movements, which can frighten them. Gradually come closer and then dip an empty hand in the water nearby while they feed. Finally begin to offer small amounts of pre-soaked pellets in an open hand, a few inches below the surface (dry pellets will float off). Once the first fish has taken food, others will follow.

Your other option is to sprinkle a pinch of fish food if they are flakes or just a few pellets into the pond and making sure that there is no excess food to avoid your pond being polluted by the remaining food.
