Additional Information:

Spirulina is a blue-green plant plankton rich in raw protein and seven major vitamins: A1, 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 Meds 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. Youll see an amazing difference when you feed Spirulina 20!

Zoo Med Spirulina 20 Review

Written by Kmuda

Some may consider the Zoo Med line of fish foods a new product. Old school fish keepers in the know will quickly recognize the product labeling and name. These are actually the Aquatrol line of fish foods, used by experienced breeders and fish keepers since 1969. Zoo Med, well known for their involvement in the reptile hobby, decided to branch into the aquatics industry with a line of fish foods. Instead of manufacturing their own, they've resurrected Aquatrol, releasing the entire line of Aquatrol products as the Zoo Med line. The only thing that has changed is the company name. The foods are made by Aquatrol, using the same ingredients.

The Zoo Med line of foods utilize home grown quality ingredients. If you review the ingredient list you'll notice an absence of the controversial preservative ethoxyquin, a clear indication that their "Salmon Fish Meal" is not an overseas product that has spent months (if not years) on boats and in warehouses. In this case, the salmon used in the creation of fish meal is Alaskan Salmon. All ingredients used in the creation of Spirulina 20 are USA products.

As each product listed in the ingredient list is listed at its dry weight, you can trust the list as an accurate representation of the actual ingredients.

Spirulina 20, as its name implies, is comprised of 20% spirulina. The health benefits of spirulina are well documented and while I will not cover them here, let me state that your fish will be healthier, have improved immunity, live longer, have better coloration, and spawn more readily if Spirulina is a component of their diet. You will not find a higher concentration of spirulina in a fish food than you will in Spirulina 20.

Spirulina 20 has become my flake food of choice. I feed it to all of my fish, even moving my 22 year old Kissing Gourami over from using Ocean Nutrition Spirulina Flakes. I prefer this over the Ocean Nutrition product because of flake size, consistency, and Ocean Nutrition's use of ethoxyquin. If you have Silver Dollars or African Cichlids, this is certainly a food you should try. My Silver Dollars go nuts over it. There is not a fish in my tanks, including even the Oscar (who steals a few flakes from the Silver Dollars), that does not consume this food with relish. This includes Angelfish, Kribensis, Dwarf Gouramis, my Kissing Gourami, and a whole assortment of tetras and livebears. The birth rate of my livebearers has improved and Emperor Tetras, who were beat up and washed out, have become vibrant, active, and colorful after only a few weeks of using this food.

This is a highly recommended product. It's what a dedicated fish keeper wants in a fish food and to top it off, it's an American product, made by an American company, made in American, using American ingredients and American labor.


  • Contains 20% Spirulina, the highest concentration of this "wonder-food" I am aware of in a fish food. If you know of a food with higher Spirulina content, please let me know.
  • Made in American using American Ingredients by American labor working for an American company
  • Palatability. Fish love it. With some flakes, the fish eat some and spit some out. I don't have that problem with this food. Even my finicky Angelfish eat this food.
  • Cost: This remains a relatively low cost food when compared to other quality brands. Big Al's carries the 4oz (Large Economy Size) for around $8. Even at my Mom and Pop LFS, the cost is around $11 for the same container.
  • Flake Size: Ocean Nutrition Spirulina Flakes is an excellent food but the flake size is really to small for feeding larger fish such as Silver Dollars. The flake size of Spirulina 20 is perfect for these fish, even large enough my Oscar steals some from the Silver Dollars.
  • Does not contain  Ethoxyquin.Ethoxyquin is a fat preservative found in almost all pet foods that contain fish meal. It's hard to escape as it is required by law to be included in any imported fish meals. Regardless, despite USDA guarantees of it's safety (they say the unhealthy affects are "dose dependent"), Ethoxyquin is widely accepted to be a cause of numerous pet ailments (cancer, liver failure, birth defects, and infertility) and has subsequently been banned for inclusion in human foods. It's absence in Spirulina 20 is a clear indication home grown ingredients are used and is a further indication of a food you can be happy feeding to your fish.


  • Studies conducted by the University of Albany’s Institute for Health and the Environment have identified significant contaminant levels in farmed salmon. “In particular, four substances that have been well studied for their ability to cause cancer-PCBs, dioxins, dieldrin, and toxaphene-were consistently and significantly more concentrated in farmed salmon.” Contamination is significant enough that the human recommendation for the consumption of farmed salmon is reduced to a “one-half to one meal per month-based on U.S. Environmental Protection Agency (EPA) consumption advisories for these contaminants. A meal was considered to be an eight-ounce portion.” It can be safely assumed that this meal is comprised of farmed salmon.
