Astaxanthin is a potent, natural carotenoid pigment often sourced from algae used to significantly enhance the red and orange, and to a lesser extent, yellow, colours in koi. It acts as a powerful antioxidant, boosting immune systems and promoting skin health, added to this feed to ensure vibrant, high-contrast pigmentation without staining white scales.
Krill is a highly desirable ingredient in koi food, acting as a natural, nutrient-rich, and palatable protein source that improves overall fish health, growth rates, and coloration. As a source of essential nutrients and carotenoids, it is particularly useful in premium koi feeds during warmer months to support rapid growth and vibrant, intense colors, particularly for red and white skin.

96% of Pellets Float
Floating koi pellets allows you to easily monitor fish health, check for injuries, and control appetite, as the fish rise to the surface to eat. It reduces water waste because uneaten food is easily visible and removable, allows for direct interaction via hand-feeding and reduces the risk of food sinking to clog filters
4% of Pellets Sink
Sinking koi pellets ensures fish that do not want to engage in surface feeding or are shy will still be able to eat well removing the worry that some of your koi and fish may not be getting what they need to thrive.
