How often should koi be fed?

Koi need feeding twice daily, once between 8 and 10 AM and once between 3 and 4 PM, at about two to ten percent of body weight, with a slightly smaller afternoon portion.

If water changes are infrequent, feed once daily in small amounts so the koi finish within five minutes. Food varies by size: fry eat infusoria and small daphnia; larger koi eat various daphnia, small earthworms, fish bits, shrimp, crab, and artificial pellets.
