    Fish love this one!

    Pros: Quality food, price fairly and fish love it!

    Cons: Flakes seem to have been beating down in shipping

    Our fish seem to be picky but they do love this flake food. I've fed Ocean Nutrition off and on for years and have always considered it a high quality food. It did seem that the flakes were beat down a bit into smaller flakes but probably from shipping, not the mfg or vendors fault. What more can I say, great food.

    Pros: my clownfish love to eat this flake

    Cons: none

    I took a page out of the inappropriate reefer's book and decided to try feeding this flake to my pair of Black ice snowflake clowns. They can't resist it. So it seems like a win to me. Plus, the container is way bigger than I expected. I'll be good on flake forlod for a long time.
