Yes, Koi fish eat meat.
Koi fish are omnivorous. They not only consume plant-based foods but also eat meat. Here is a detailed explanation of the dietary habits of Koi fish:
The Omnivorous Nature of Koi Fish
Koi fish have a very wide-ranging diet, which includes mollusks, benthic animals, fragments of higher aquatic plants, fine algae, etc. They can even dig out food from the pond bottom mud. They are highly adaptable to food and are almost not picky eaters.
The Carnivorous Aspect of Koi Fish
Koi fish do indeed eat meat, such as small fish, insects, earthworms, mealworms, etc. In nature, Koi fish will prey on small fish and other aquatic organisms. Especially when food is scarce, they may even bite smaller grass goldfish or goldfish.
Feeding Meat in Artificial Cultivation
In artificial cultivation, Koi fish can be fed with chopped lean pork, beef, mutton, chicken, duck meat and other animal-based baits. They can also be fed with small fry, bloodworms, etc. These meat-based foods can provide Koi fish with abundant protein and nutrients, promoting their growth and health.
Precautions
Risk of Cross-Infection: When feeding live small fish or insects, it is necessary to pay attention to disinfection to prevent Koi fish from being infected with parasites.
Appropriate Feeding Amount: Meat-based foods should be used as a supplement and should not be fed in excess, so as not to affect the water quality and the digestive system of Koi fish.
In conclusion, Koi fish not only eat meat, but also appropriate feeding of meat-based foods in artificial cultivation is helpful for their healthy growth.
