Why You Should Always Feed the Best Koi Food

There’s all kind of different fish feed available on the market. Most people don’t think twice about what kind of feed they should get for their fish. It’s easy to get tempted to go for the cheapest generic feed that’s advertised to be suitable for all fishes. However, without taking your fish’s nutritional requirements into consideration you’re just feeding them fodder.

The Koi fish isn’t a picky eater by any means. Owing to their omnivorous nature, they have a wide selection of nutrients available to them. They can consume everything from plants to grains, and even small sea life. But if you’re looking to get your Koi living in optimal conditions, you need to have the best Koi food to feed your fish. There are a number of benefits you can experience from that. We’ve listed some of the key reasons below.


Although Koi can consume just about anything, it doesn’t all get digested in the same way. More complex food matrix blends will tend to take longer to digest. They may even take a toll on the fish’s ability to digest food. Since Koi are cold-blooded, they don’t have traditional stomachs. This means they cannot store food in their stomach to digest it in one go. They have to individually digest food as it enters the fish. Some hard to digest food will need warmer temperatures to ensure that the food gets digested properly without any issues.

Water Quality

One of the things people don’t consider when buying fish feed is how it will affect the water quality. By having mineral-rich fish feed you can cause the water turbidity to rise and create an ion gradient for you Koi. It will also cause your water to get cloudy from bacterial spread from waste food and fish excrement.

Better Immunity

The best Koi food is meant to be more than just a source of nutrition for your Koi. It also manages to help create better immunity for you Koi. Generally, the Koi used in display aquariums tend to have weaker immune systems. Getting a good fish feed source can help your Koi build immunity against various diseases and aquatic parasites.

Advanced Growth

The basic function of any kind of food source is to help provide enough nourishment for growth. The best Koi food will help your fish grow at a decent rate. You can see your Koi develop much more naturally and quickly over time.

Koi Color and Patterns

Koi are meant to display fish which is why you want to keep them properly fed. Koi have the ability to express more vibrant visual patterns and colors as they get healthier. The better the Koi food is, the better you can expect those patterns and colors to be vibrant and visible.

What to Look For in Best Koi Food

Now that we know how important it is to have the right Koi food, it’s time to look at what we should look for in the food. Generally, you want to make sure that whichever feed you get is appropriate to your Koi and its requirement. We’ll be looking at some basic ways you can judge the actual quality of the Koi feed.


A fat source is necessary for the Koi to build up fat. This will help the Koi brave colder climates and help maintain its body heat. It will also give it a store of energy that is easily accessible to it.


Protein is very important for growth and development of bones, cartilage, skin, and enzymes. One of the easiest sources of protein in Koi feed comes from small aquatic life. These include brine shrimp, and even anchovies and fish meat. Since Koi are natural omnivores they can easily digest small portions of meat. It’s a good idea to have at least 35% protein in your feed.

Color Supplements

While not essential to the Koi’s overall nutritional health, color supplements may be something you’d want in your feed. These include algae that a Koi will feed in its natural habitat. Algae help enhance the color of the Koi’s vibrant colors and make them stand out.

Vitamin and Mineral Resources

Last but not least, a decent Koi feed needs to contain the appropriate amount of vitamin and mineral resources. Koi can make good use of these sources to maintain their health. Vitamin A, C, B, and K will help your fish regulate its bodily functions better and maintain it better. They can also build their immunity up and fend off any endo-parasites or diseases.

Final Thoughts...

Now that you know what to feed your Koi, you can make sure they maintain their health to an utmost degree. You can now enjoy a stunning aquarium of healthy, stunning, and vibrant looking Koi that will manage to stay in peak fitness for a long time coming.

If you think that your fish food might need switching, consider trying out Kaytee Koi’s Choice Premium Fish Food and document if the health your fish and tank improves over time. It’s a trusted product for a lot of others, so give it a try.
