My Aunt used this for her outside koi pond, and she said that the fish really liked it. She found that the fish were more active, and colorful.

Pros: koi ate this stuff up!

Cons: none

Our koi immediately surface for DINNERTIME with Koi Premium Fish Food. The pellets are clean and easy to handle. Children love to feed the fish and watch them surface and open their mouths. It's fun to see them jostle to get to the food first. Our Koi are rather shy, but they never fail to surface when we toss them Koi Premium Fish Food. Their body colors are a brilliant orange, deep black and pristine white. We like the can so that it can be resealed in between feedings and can keep it outside where it is handy to the pond.

Pros: Easy to handle, floats on top, lightweight, clean, low odor

Cons: A plastic container would be more weatherproof.

We use this on our outdoor pond, the Koi seem to enjoy it

Pros: Lasts a lnng time

Cons: none

We were given some of this product and the fish seemed to like it. However, it did not seem any better than the inexpensive small floating fish food we have used from Southern States for years.

Pros: Fish seemed to like it

Cons: expensive

We feed this to the fish in our pond, they love it.

Pros: Fish like it

Cons: None
