Koi are omnivorous fish, and their food sources are extremely extensive, including both plant and animal foods.
The main food sources of koi include:
Mollusks and benthic animals: Koi will eat fragments of some mollusks and benthic animals.
Fragments of higher aquatic plants: They will also eat fragments of higher aquatic plants.
Tiny algae: Tiny algae is also one of the food sources for koi.
Live baits: Koi like to eat live baits such as earthworms, small fish, shrimps, insects, and snail meat.
Animal baits: They will also eat animal baits such as chicken, beef, animal liver, crab meat, mealworms, and superworms.
Plant foods: Koi will also eat fresh aquatic plants, plant rhizomes, algae, fruits, vegetable leaves and other plant foods.
Synthetic feeds: For koi kept at home, artificially synthesized fish feeds are more recommended. These feeds are comprehensive in nutrition and convenient to feed.
Koi have a very wide range of food preferences and are highly adaptable to food, so they are relatively easy to raise. However, when feeding, it is necessary to pay attention to proper amount, regular timing, and fixed points to ensure the healthy growth of koi.
