Hi Silk Koi Food 01:35

An introduction to the koi food, Hi Silk-- loved by all koi, and very effective in growing them big. View Hi Silk - , A characteristic of HI SILK is that we’re using this ingredient. Silkworm pupas. The primary ingredient is silk cocoons, but famous koi breeders in Niigata have been using these silkworm pupas for ages, in order to make the famous koi that we all know and love. The fact that it’s still being used in this is one of HI SILK’s main features. Kois love these silkworm pupas. The most important thing for koi food is that the koi likes it, that it eats a lot of the food. That’s the main reason for them growing big. This is the color-enhancing koi food that’s been released recently, and it’s said that color-enhancing foods don’t taste good, but that’s not the case for this one. The koi eat this a lot. So this food has the two benefits of growing the koi big, while also enhancing its red color. In places like Hawaii, the water temperature is most likely high, so this would be very good. It works amazingly in countries and areas with high water temperatures. Thank you very much. ---------- View our Farm - Bid in Koi Auction - See All Our Koi - Recommended Koi Pond Supplies & Memorabilia - Visit our Koi Stores in NJ, NY, FL - ---------- Let us know what you think in the comments!

    Koi are gobbling it up, however they have never been finicky eaters. It is nice to know I'm feeding quality food and will see results over the coming weeks/months.

    I ordered an 11 pound bag of Hi Silk with Medium pellet size. The size is definitely NOT medium, they are very small and I was disappointed. I hope you can address this problem

    My koi are not picky eaters, but they will knock each other out of the way to get to Hi Silk. I buy a bag every year. I tend to feed it when the hottest part of the summer is over and the temperatures start to drop.
