Now that Hikari is offering flakes (I got the free samples in the mail) I'll be using that as I LOVE their products. Previously I've been using TetraMin. But my fish get quite a variety of foods, from flakes, to sinking granules, to other kinds of flakes to frozen food to live food to freeze dried food, Lol. If I see something that looks good I tend to buy it as I like variety. Due to some freeze dried food I won in a couple of raffles, I'm stocked for life with that stuff (which I don't feed often as I think other stuff is better than freeze dried).
