My clownfish actually pick these out of the mix over the brine shrimp—the spirulina really brings out their orange. The flakes stay crisp and don’t turn the water cloudy, which is a win after a week of feeding.

My tetras go absolutely crazy for these flakes—the color enhancement from the spirulina is noticeable within a week. I especially like that it works for both my freshwater and marine tanks without any fuss.

I was amazed at how much richer my clownfish's orange color became after just two weeks of these spirulina flakes. They sink slowly so everyone gets a chance to eat, even my shy blenny.
