ADditional information


Spirulina is a blue-green plant plankton rich in raw protein and seven major vitamins: A, B1, B2, B6, B12, C, and E. It naturally contains beta carotene, color-enhancing pigments, and a whole range of minerals. In addition, it contains all essential fatty acids and the eight amino acids required for complete nutrition. Zoo Med’s Spirulina 20 Flakes contain a full 20% Spirulina and provide a complete high protein diet for freshwater fish, marine fish, goldfish, crustaceans, and invertebrates. Research has shown that fresh and saltwater fish exhibit superior growth, maturity, energetic behavior, and more elegant coloring when fed Spirulina. It is also well documented that Spirulina improves egg production and hatching rates, stimulates the reproductive processes, increases survival rates of younger fish, and arouses the appetite of fish. You’ll see an amazing difference when you feed Spirulina 20!

  • Perfect for African Cichlids, Swordtails, Platies, Guppies, Mollies, Saltwater Angels, and Tangs.
  • For daily feeding of fresh or saltwater fish.
  • Natural color enhancer.

“We were thrilled to see Spirulina 20 back on the market! Even better, the line has expanded to cover Earthworm and Plankton flakes. Our fish took to both new foods right away and have done very well on them. We’re happy to make room on our shelves for the new foods.”
