Food is the key to having healthy koi fish. Feeding your koi a high-quality diet rich in the vitamins and minerals they need as fuel to grow and thrive in an aquarium will result in healthier and more vibrant fish.

Not all koi fish foods are alike, and some are filled with unnecessary ingredients that are not beneficial to your koi’s health. Although some foods might be labeled for koi, it does not automatically mean that the food in question truly meets your koi fish’s nutritional requirements.

It is important to note that koi fish are omnivores, which means that they should primarily consume a diet rich in both animal-based protein and plants. A healthy diet will influence your koi fish’s color, growth, and overall health.

Some foods are considered to be low-grade and made of fillers that do not benefit your koi, which is why we have created this article to give you an honest review of some of the best koi food brands available!

Choosing the Best: What to Look For

When it comes to choosing the best koi food for your fish, the main factors to consider will include the price, nutritional content, and the volume of food. Here is how to consider the best koi fish food according to these three factors:

Rate of Decomposition

This simply refers to the rate at which the food decomposes once it has been exposed to water. Some foods will take longer to soften and start to crumble in the water, whereas other foods will rapidly start to dissolve and lose their nutrition over time if your koi do not eat the food quick enough.

You want to choose a food that does not deteriorate too fast once it has been placed in the water so that your koi can have a chance to eat the food and still retain the nutrition that would otherwise have been dissolved in the water. Choosing a portion of food that does not dissolve quickly in water will also help benefit your pond’s water quality because it means less food is being introduced into the water column and then creating waste.

Nutritional Content

This is a very important aspect to consider when it comes to choosing the right food for your koi fish. The nutritional content will consist of the food guaranteed analysis which is the percentage of protein, fat, and fiber the food has, along with the types of ingredients contained in the food.

You want to look for a food that contains very few fillers which only helps to bulk up the weight of the food but has little to offer koi fish in terms of nutrition. If you find that the fillers (starchy, carbohydrate-rich ingredients) are listed within the first few lines of an ingredients list, then it can be assumed that the food is full of fillers and not worth buying. You want a food that contains beneficial ingredients for koi such as wheat germ, fish oils, linseed oils, spirulina, and other animal or plant-derived proteins and fats.

Color Enhancement

Koi is adored by fish keepers for their striking coloration, so you want to take into consideration the color-enhancing benefits and ingredients the food has to offer. This is why you will see a lot of koi foods labeled as ‘color enhancing’ or have other fancy names such as ‘vibrance’ as this is a good indication that the food contains some sort of ingredients such as spirulina, krill, or shrimp that helps to improve and maintain a good coloration in koi.

Color enhancing foods can also help make your koi’s red, yellows, and white colors more vivid once they have been eating the food for a few weeks. These foods will not directly change the color of your koi, but they are great at helping to make it more attractive.

The Different Types of Koi Fish Food Pros and Cons Compared

  • Flake Foods: Thin and colorful pieces of food that are the most readily available and cheapest.
  • Gel Foods: This comes in a powder form and needs to be added to water and refrigerated before being fed to koi.

Let’s look at the pros and cons of each type:
