DAPHNIA CULTURE 200-PACK: Provide live food for fish in a freshwater or brackish water aquarium. Commonly known as “water fleas”, daphnia are a nutritious food source with essential vitamins that support the wellness of live shrimp, live betta fish and more. LIVE FOOD FOR FISH: Freshwater daphnia can be used as betta fish food, guppy food, axolotl food, and more. Daphnia will multiply quickly, producing daphnia eggs that can be raised to provide live food for betta fish, live minnows and other fish species. AQUARIUM ALGAE CONTROL: Utilize daphnia as an organic algae remover for aquariums and establish a continuous food source in your fish aquarium with this daphnia kit. Raise your own daphnia eggs in a daphnia tank with live aquarium plants instead of choosing freeze dried daphnia. WATER FLEA FOOD: Species like Daphnia magna and Daphnia pulex thrive in freshwater or brackish water environments, and are often used as betta daphnia food, goby food, and more. Daphnia (Daphnia magna), also known as Water Fleas, are small, kidney bean shaped invertebrates that are native to rocky pools along the Atlantic coastline of the northeastern United States. Many members of the genus are also native to brackish and marine habitats. Daphnia are filter feeders, so green water is recommended. They regularly consume zooplankton and phytoplankton. In the aquarium, Daphnia are a superb food source for micropredators, especially small fish. They are often effective in bringing out vibrant colors and spawning behaviors in fish. Daphnia can reproduce both sexually and asexually. Females can produce eggs as often as every four days in the right conditions. Daphnia will reproduce between temperatures of 64° F (18° C) and 71° F (22° C) or above. They will reproduce at a very prolific rate, and one starter culture is often enough to produce a virtually endless supply of live food, especially if cultivated in a separate tank where they are not outnumbered by predators. Our Live Daphnia Culture is available in packs of 100, 200, and 300 — more than enough to start a strong population.
