What does koi fish eat?

Koi fish is an omnivorous fish. Generally speaking, fragments of molluscs, benthos and advanced aquatic plants, and even tiny algae can be used as fish food in koi fish, and they can also dig out some food from pond sediments. With the growth of fish and the change of seasons, their food intake also changes. In summer, koi fish has the highest feeding intensity, but in winter, it doesn't eat at all.

Koi fish has a wide adaptability to fish food and is not strict with living conditions, so it has strong vitality. Of course, now synthetic fish food is also the first choice to feed koi fish, and it is rich in nutrition, which makes koi fish healthy, beautiful and energetic.

Plant feed:

Of course, the most ideal feed in koi fish is animal feed. However, in the absence of animal feed for various reasons, plant feed can be used as emergency or life-sustaining auxiliary feed. Weeds and aquatic plants are common, among which weeds are one of the smallest species of seed plants. Plants are as small as sand and have no roots, so they are more nutritious.

The other is duckweed, which has filamentous roots. Koi fish eats when he is hungry. Generally, he can only feed the older koi fish, not more. Before feeding, carefully check whether there are pests and eggs, or soak in low-concentration potassium permanganate solution for a while before feeding, otherwise it is easy to bring in germs and pests.
