Zoo Med’s Spirulina 20 fish food flakes are perfect for African Cichlids, Swordtails, Platies, Guppies, Mollies, Saltwater Angels and Tangs. For daily feeding of fresh or saltwater fish. Natural color enhancer. 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 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. Made in the U.S.A.

Great for fish and great for budget!
My fish love this food. Because it is spirulina and not the orange food, the water does not look brown between weekly water refreshment. The fish are in good health, are not fighting with each other due to hunger and it is easily digestible by them.The size of the container works great to feed my fish in our 90 gallon tank.

Excellent food
I have fed this to my fish for a very long time. Some of my fish are over 16 years old. The ingredients, after researching what is considered high quality food, are good.The fish like it so no complaints from them.The only complaint I have is the majority of the flakes are huge. You have break up the pieces. Towards the end, it is mostly powder and makes too much of a mess to feed. You could save the powder to feed live bearer fry but fish of any size would not be able to eat it. When I travel, I don’t use this in my autofeeder and I have some crisps I use for that purpose.

Superb Food of Superior Quality
Having kept fish for over 35 years there are few foods I haven’t tried. Along time fan of Zoo Med for a multitude of reasons. Zoo Med uses top grade ingredients and the foods are made here in the United States.Unlike so many imports from China Zoo Med foods are free of filler, sub par ingredients and what is most important free of Ethoxyquin. Ethoxyquin is a toxic pesticide often touted as a preservative – It’s long been banned from dog and cat foods however due to poor regulation lower end foods continue to use it.Studies have proven that Ethoxyquin even in trace amounts is especially lethal to fish. Studies that support this can be confirmed by simply looking ethoxyquin up on Wikipedia and follow the links to the findings.Regarding Spirulina 20 – this is an outstanding, naturally color enhancing food. Packed with protein at 45% this food is perfect for fish ranging from African Cichlids to Fancy Ornamental Goldfish – both of which I keep in a never ending accumulation of fish tanks.Spirulina is a plant based plankton often referred to as “the perfect food” it’s packed with protein, vitamins A1, B1,B2,B6,B12 and vitamins C and E. In addition Spirulina is rich in eight essential fatty amino acids – it’s a wonderfully healthy food.The flakes are huge which makes feeding a breeze – I have a huge Red Devil Cichlid who goes crazy when he sees the jar. My Ornamental goldfish and other Cichlids are equally crazy for it.Perfect for salt, fresh and brackish water fish – Spirulina 20 is an absolutely wonderful food which will enhance both the color and health of most any fish you keep.

False claims on packaging
I’m not going to say it’s a bad product, but most of the ingredients are pointless and – much more importantly – there are quite a few erroneous statements on the package.Let’s start with the obvious: Spirulina. That ingredient is the main reason I purchased it, and as a biology major who directly studied Spirulina, I know quite a few things about it.The package claims: “Spirulina is a blue-green plant plankton” False. Spirulina is a cyanobacteria. People in marketing like to call it a blue green algae, but it is neither an algae nor a plankton. It’s not even remotely related to plants. (the only similarity being that both are photosynthetic) That makes it better though. All plants have cellulose based cell walls that are indigestible, but Spirulina contains mucopolysaccharide cell walls which was fully digestible.”… rich in raw protein” True! Actually, Spirulina is 65% complete protein. More protein than is in meat, and at a much higher quality. There is no reason to include Salmon at all, except that Salmon is CHEAPER. So they used meat as the main ingredient, added Spirulina, then claimed it was Spirulina based to use the buzz word. A pure Spirulina flake product would be far superior to this in every way, but it would also be more expensive.”and seven major vitamins: A1, B1, B2, B6, B12, C, and E” True! Although it should be pointed out that the B-Vitamins are actually analogs in the form of Cyanocobalamin, but all animals – including humans – can safely convert this to those Vitamins so it’s close enough.”…contains beta carotene, color enhancing pigments, and a whole range of minerals.” – true, but not well written. Spirulina has a unique pigment that no other organism – not even other cyanobacteria – has which has DNA repair properties which in humans is related to it’s benefit in treating radiation sickness, but in fish probably helps enhance their color when combined with all the nutrients. The minerals though really depends on the growing medium. If using evaporated sea water, probably. Even if it isn’t grown in the best water it will still be rich in macro minerals like iron and copper.”… contains all essential fatty acids” True!”… and all the eight amino acids required for complex nutrition.” Not true! Spirulina is a complete food, don’t get me wrong. Even humans can live on it and nothing else. It is missing the D-Vitamins though, and although humans can produce Vitamin-D through light exposure, the consensus is that fish do not synthesize vitamin D. Thus MUST obtain it from their food so the Spirulina does not have every amino acid essential to them. Of course, since it contains so many additives that is moot in this case. The Salmon contains plenty enough for use.”Spirulina 20 flakes contain a full 20% Soirulina” and since this is listed second on the ingredient list, it’s probably in the range of 60% Salmon, 20% Spirulina, followed by all the other junk like Wheat, and Yeast, and Corn Starch, and Dried Krill, and Shrimp, and… well… it says Plankton, but since they don’t seem to know what Spirulina is I can’t really trust anything else on the ingredient list. The ingredients specifically say “Spirulina Algae Meal” which is either a complete lie or is ambiguously doing so to include algae contaminants without having legal trouble.Honestly, I would have given this 5 stars if only they weren’t trying to lie to the general public. It otherwise seems like a good product. Better than most other fish food products.

great dog treat.. oops
I got these for my spoiled fish. They were not overly interested, but did take a nibble or 2. They are spoiled, with frequent brine shrimp and other live food, so even a nibble on flakes from them is a good thing. I would like to say how they did after a few weeks, but… I went to work and my dogs devoured this. They licked the jar clean. But, isn’t that a glowing review in itself? They know better, they took a risk because this smelled like a worthy reward. Nutrient density and freshness drew their attention. Taste made them eat every last flake. Not the intended audience, but a great thumbs up regardless 😀
