How to choose the best food for Koi fish and other pond fish

“A human being can survive only living on a diet of hamburgers and fast food.” If you believe this statement is true and you also have a Koi pond in the backyard, chances are you think there is little difference between fish as food available in the market. “A cheap Koi meal is exactly the same as the expensive brand with a different label.” This is also another comment often expressed by Koi aficionados who opt for diet for their fish based solely on price. And while it is certainly understandable that a pond owner would save money, all fish foods are not the same. Here are some of the key factors that every Koi holder should consider when choosing a food for Koi fish and other pond fish.

Nutritional analysis

You never go to a restaurant and eat everything the server puts on your plate if you first do not know what it was about. The same logic should be applied when selecting a diet for your Koi and other pond fish. The different varieties of Koi foods are formulated to be used for different types of year. Food varieties in each season, for example, contain minimal protein content and are designed for rapid digestion. Food crops, on the other hand, contain high amounts of protein and are ideal for summer feeding.

Feeding a fast-growing fish meal during the winter can cause serious health problems. As the water temperature drop, metabolism decreases Koi. Growth foods can be easily digested and can literally begin to rot inside the Koi fish, causing disease and possible death. The food in catfish is designed for the short term supply of fish feed only. These foods are not designed for long-term supply, and they do not meet the special nutritional requirements of Japanese koi.


Many diets in the fish market contain basic fillings like corn, which are not very digestible for koi and other pond fish. This results in more fish waste products, which can cause more work for the pond filter and cause a decrease in water quality. Whenever possible, it is best to avoid fish feed containing fillers and other low quality ingredients. Many varieties of Koi foods on the market contain ingredients designed to mimic the natural koi diet, which are actually ornamental, wild carp.
