DainichiKoi Fish Food, All-Season 5.5 lb Bag – Medium Floating Pellets (5.5 mm) for Koi, Goldfish and Pond Fish – Cold-Weather and Winter Formula – Easily Digestible Wheat Germ Formula

Great for our koi. Quality koi food.

This is absolutely the best food you can buy if you care about your fish. Is there cheaper options? Sure but if you have the option to feed your kids grass fed ribeye steaks or cheap burgers from McDonald’s which would you choose. Customer service is fantastic as well.

We live in S. California. We have three koi of three sizes and three ages, like the story of the three bears - old small-size, old medium-size, and young large/huge. They all eat this medium size food easily, and they like it and we haven't had any diseases or loss of weight so it must keep them healthy. It doesn't take much, just a few pellets every several days (less in winter) to keep them happy. Of course they beg, but put a pellet in and you'll find them just pushing them around with their noses if they are fake-begging. We have fed the various koi this food for 15 years. It is expensive but it doesn't take many pellets - foil-lined sturdy bag, lasts several years.

Been feeding this brand of food to our 6 koi fish for years. Fish are thriving on it.

I have been feeding this to our koi (10+ individuals) for years. They are in a controlled indoor environment so we do not face the normal concerns with changing seasons and temperatures. This is a great all-around food. I switched to a cheaper type of food when I irresponsibly ran out of Dainichi. I got it from a local store in Minneapolis that I have patronized for years and they are very knowlegable about all aquatic life. They didn't think there was any reason to worry about the switch (and neither did I), but within a couple weeks I had lost two fish - one koi and one goldfish- and the other koi looked sick and poorly. I don't believe this was a coincidence. I related the tale to the fish store and and I switched back to Dainichi All Season immediately after I lost the two fish within days of each other. The remaining live fish perked up immediately after a good water change and moreso after a couple days of the Dainichi food. I will never switch again. On the upside, I did find that the "killer" koi food makes a fantastic tomato fertilizer, so it wasn't a TOTAL loss. Hedge your bets, be good to your pets, stick with the Dainichi good stuff.

No, I don't work for this company. I purchased a lower-priced (I thought) fish food that came in a nifty bucket. Made it look like a real bargain. But it did not smell right. I looked at the ingrediients and it was mostly meal. I remembered Dainchini (amazingly a made-in-America company) from the past and how my koi went psychotic in excitement when I feed them it. So I paid for it through Amazon. It comes in a vacuum-packed like bag, and at first glace looks like it is a lot less food. But I poured it into the higher priced looking bucket the previous meal-based koi food was in, and it was approximately the same amount (without the nifty bucket). Dachini is 1/3 protein (krill and shrimp). You can see and smell the difference, and so can fish.

Use to buy it here on Amazon but since shipping is getting too much, I now purchase online at another retailer for less. Also, Dainichi seems to make it difficult and more expensive to buy. Next time will try Mr. Kodama Koi Food that has very good reviews and free shipping.

My wife and I purchased this product about 8 months ago when we purchased our new koi. We have noticed when we have used other koi food that the fish didn't grow nearly as fast as they do with this product. This is caused our fish to grow astronomically. When we bought the fish I thought it's going to take forever for these little teeny guys to grow bigger and this food has caused our fish to grow very fast and very colorful. This is a great product and worth every penny. Other products on the market are full of air. Respectfully Dave
