These six foods were chosen due to their quality, price, ingredients, customer reviews, and other amazing qualities.
Let’s take a closer look at each and see which best suits your new koi babies!
Made without preservatives, this Sera Micron Nature food is natural and digestive health-friendly, providing a formula derived from krill protein and spirulina.
The natural plankton food formulation provides crude protein for optimal development, with the ratio being 50% spirulina and 15% krill. This means the formula contains both zooplankton and phytoplankton, providing a full spectrum of beneficial nutrients from multiple sources.
The finely milled food is perfect for fish and amphibian fry and floats at the surface of the water to encourage surfacing and allow a better monitoring opportunity to ensure your koi fry are getting enough food individually.
This formula mimics the appearance of plankton and other naturally eaten food sources and is easily digestible which prevents pond pollution and cloudy water development, too!
Good for larger volume breeding efforts, this bulk koi food is affordable and high quality, providing your koi fry with a good base nutrient level to amplify their growth and coloration development.
Rich in amino acids, this product sits at around 40% protein, providing a balanced amount for muscle and tissue development in new fry.
The powder-crumble style product is designed so that half will sink immediately, allowing the koi fry to eat freely and the other half will sink much slower, encouraging surfacing and movement to increase muscle development and movement control.
The brand does note that this product is primarily suitable for pond enclosures and that in tanks with filtration, the food may be quickly sucked up, preventing the koi fry from eating enough.
With a slightly elevated protein level, this food is perfect if you want to grow some really big, beautiful koi fish.
Perfect for koi babies in tanks and ponds alike, this food is dense enough and floats for long enough that it will not be easily sucked up by a filter, giving the koi fry the ability to eat freely and consume enough at each feeding. Plus, the floating nature encourages movement and swimming, which enhances muscle development over time.
The brand uses fresh salmon meal as its base, along with other nutritionally vital ingredients like dried yeast, spirulina, fish oil, and vitamin supplements to create a powerful food that really packs a nutritional punch.
They also hand package every single order and bubble wrap them tightly to protect the packets in transit and ensure you always have food on hand with no mishaps or shipping errors on the brand’s end.
Designed specifically as a fry starter food, this daily diet formula contains no fillers, preservatives, or artificial pigments, delivering exactly what your koi need without any frills or unnecessary extra ingredients. Instead, each feeding provides amino acids, protein, vitamins, and vital minerals directly to your fish.

The brand also claims that the food enhances the coloration and lifetime of your koi, as well, providing them with the perfect start for a healthy, long life.
This food is also suitable for a host of other freshwater fish and tropical fish, as it provides necessary nutrients and has a clean water formulation that is easy to digest across the board.
