First two year that I had koi fish they were slowly growing about an inch and half each year. But since I changes to feed them with this food they growing up very fast ab9ut 3 inches withing 3 months plus they also very healthy.

Love the food

I had been feeding our koi some better quality foods which were supposedly color enhancing and was still seeing the colors disappear. I switched them to this brand and could not believe how much color I was seeing return! Fish that had gone all white started getting their black spots back on them, and even the red has begun coming back. I began feeding it to them rather late in the season last year, and I'm really looking forward to seeing how much color they get from feeding it to them all season long this year! Not cheap, but worth the money in my opinion.

My koi seem to love this food

Good food but for the new price I will stick to saki
