I know nothing about their fish food but checked into them quite a few years ago. Their feed was about half what others were selling for. So, I called the head of Purinas fish food area, Dr. Mark Griffith, and asked him. He told me that their retail price was less than he paid for ingredients so I passed. I PERSONALLY consider them an unknown and their price is about the same as the major brands that I have good experience with.
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
