Fishers Koi Diet+
Fisher's Koi Diet+ is an all-new, improved daily food for both koi and goldfish kept in ponds, tanks, and aquariums. It carries on the Fisher's tradition of sustainable, US-sourced high-quality ingredients with all-natural preservatives, loads of spirulina, and natural color enhancers that bring out brilliant reds, oranges, and whites. Pair it with healthy fish from our nutrition and fish food collection.
Why Fisher's Koi Diet+
Fisher's builds this formula for the long-term health and color of prized koi and goldfish. Spirulina and natural color enhancers deepen pigmentation, while omega-3s, vitamin C, probiotics, and beta-glucan work together to support digestion and immune strength. The smaller pellet sizes float and soften quickly, encouraging the natural foraging behavior that keeps koi active and engaged at feeding time.

3mm is the right choice for smaller koi, goldfish, and mixed ponds where the smaller pellet is easy to eat and promotes natural foraging. 5mm suits larger koi and show fish that prefer a bigger bite. Both pellets share the exact same complete formula, so you can match the size to your fish without changing their diet.
Feeding Guide
Feed two to three times per day, offering only what your fish finish in a few minutes. In ponds, feed when water temperatures are consistently above 50°F; as temperatures drop below 50°F a koi's metabolism slows, so reduce and then stop feeding for the season. Remove any uneaten food to keep water clean, and support pond clarity with FritzPond Clarifier.
