    A vital staple to have in any tank with Herbivores

    Pros: Follow feeding guidelines and supplement with NORI sheets for a treat

    Fresh smelling, floats and appears to digest easily with out bloat. Supplement this with Nori sheets and the tangs go wild

    Go crazy!!

    Pros: Well balanced, palatable fish love it and does not cloud water

    Cons: Nothing thus far

    I have a community tank mostly highlighting tropical angle fish along with mollies and some tetra’s. I was looking for a formulation that seems to be pretty complete including vegetable product. I am using the Formula Two Flakes for tropical fish and the fish “go crazy”. They love it. I’ve been using the product for about a month now and the fish look great, healthy with very nice color. I like the large flakes because I can crush them to the size I want when needed. I highly recommend this food.

    Fish love it but crumbles easily/pulverized in shipping

    Pros: Fish love it!

    Cons: Flakes break down into almost unusable particles before you get to the bottom.

    I have been using this for years and any tangs I have had have always loved it, but the flakes break down into tiny particles inside the container before you get 2/3 of the way through it. Ordered 2 containers last week and they arrived already pulverized. Must have a lot of dye, it will turn your skimmate green.
