The ideal salinity for brine shrimp is 30 to 35 percent, so they almost never occur in low-salinity environments. Because they cannot survive in low-salinity environments, they have adapted to thrive only in very high-salinity conditions. They are mobile thanks to a rhythmic beat of their appendages, and breathe through feather-like plates on their legs. Male brine shrimp have larger and modified second antennae, and ovulate every 140 hours.

Phytoplankton
Phytoplankton is what these tiny creatures eat. They feed on algae wafers and flakes. Unlike a lot of other shrimp species, brine shrimp are not able to eat vegetables and fruits, but they do eat phytoplankton. These organisms are also important food sources for planktivorous animals like anemones and moon jellies.
Phytoplankton is the food of the algae that the brine shrimp consume. These microscopic animals are also the foundation of fish larviculture, and they provide nourishment for larval fishes. Other organisms that are sometimes consumed include ciliates and trochophore larvae of bivalves, and some are harvested in large quantities from the wild.
Algae
The majority of the diet of brine shrimp consists of plankton. While shrimp are omnivorous, their primary source of food is algae. In their natural habitats, they can be found in both the fresh and oceans. Despite their omnivorous nature, they are not harmful to humans or to the environment. These small creatures play a critical role in their ecosystems.
The food that brine shrimp eat is microbes, including Infusoria and green water algae. You can also feed them egg yolks, fish meal, soybean powder, and powdered spirulina algae. They do not need to eat live food, but you should provide enough to stimulate growth of bacteria in the tank. Then, wait a few weeks. Once the adults have hatched, you can harvest them as you would Nauplii.
Spirulina
While freshwater fish commonly eat brine shrimp as a source of nutrition, these creatures don’t have much nutritional value. Thankfully, you can buy gut-loaded brine shrimp that provide the same nutritional attributes as other fish foods. Usually, these types of shrimp are used to entice finicky fish to eat frozen foods. Hikari’s Spirulina Brine Shrimps are gut-loaded with the nutrient-rich spirulina algae.
Spirulina is a powdered blue-green algae that is highly digestible by fish and invertebrates. It is spray-dried and contains over 1,500 mg of carotenes per kilogram, which are essential for fish’s vibrant colors. When mixed with freshwater, Spirulina helps improve the health of fish. For larval shrimp, it’s best to use a mixture of spirulina powder and freshwater.
Flakes
In their natural habitat, Brine Shrimp eat microscopic planktonic algae. While this is not possible in captivity, brine shrimp can consume some algae. If you want to feed your Brine Shrimp live prey, consider flakes. Flakes are easy to digest and are also highly nutritious. A few types of flakes are suitable for brine shrimp. You can also try fish meal and hard boiled egg yolk.
While the majority of brine shrimp diets are plant-based, they can be adapted to other types of diets when cultured. Flakes, spirulina, and algae wafers are the most common sources of food for brine shrimp. However, these species cannot eat cyanobacteria, seaweed, fish food, or eggs from other animals. Even coral and sea monkeys are not safe for brine shrimp.
Algae wafers
Algae wafers are a staple in the diet of aquarium fish. They come in a variety of shapes and sizes, but most are round or cube-shaped, with ridges on one or both sides to help them break up easier in the aquarium. The algae wafers are also made of fish meal, soybean flour, and wheat flour. Algae wafers are a great way to provide a healthy, natural diet for your shrimp and other fish.
Brine shrimp are not vegans, and their diet is rich in protein, as they eat both algae and spirulina. Algae wafers are not harmful to your fish, but if your cardinal tetra starts scratching on rocks or scratching the glass in your aquarium, he or she may be allergic to algae wafers and stop eating them. The algae wafers may not provide sufficient nutrients and cause malnutrition.
Spirulina flakes
Brine shrimp are a type of discus, which means they eat a mixture of plant and animal ingredients. The ingredients in discus food include natural pigments and vitamins. The resulting food is a perfect balance between protein, calcium, and phosphorus. They can also eat a wide range of other foods, including fish and meat. These foods are also popular with aquarium hobbyists and are used as a source of high-quality protein.
Many fish keepers prize ornamental species for their colorful appearance, and a vibrant color can be an attractive selling point for their products. However, rations meant for food fish often lack the carotenoids needed to prevent color fading in ornamental species. Spirulina in the diet can provide a cocktail of carotenoids that ornamental fish need to maintain vibrant colors. The blue-green substance has more than ten times the b-carotene found in carrots.
