My koi are in an indoor aquarium rather than in an outdoor pond. Would it be okay to give this type of food to them?

Best koi food I tried yet

I really like this koi product. Great packaging. Doesn't cloud the water. I was looking for something where the first ingredient is protein and not grain. Pet food

I really like this koi product. Great packaging. Doesn't cloud the water. I was looking for something where the first ingredient is protein and not grain. Pet food stores love to sell overpriced garbage. This looks like actual food!

The Ingredients Make the Difference

Our koi love the food and the ingredients make the difference. I’ve been feeding Mazuri for the last year. The health, color, and growth of our fish is notable

Good value

The fish really like it. It's a good value and I can buy a big bag. I don't feel bad when everybody wants to feed the fish

Good product

This brand although pricey provides a good balanced diet that keeps my fish healthy and vibrant. Because it contains wheat germ the transition into hibernation

This brand although pricey provides a good balanced diet that keeps my fish healthy and vibrant. Because it contains wheat germ the transition into hibernation is easy and safe. Worth the money in my humble opinion.
