Live Daphnia are microscopic crustaceans prized by aquarists as a nutritious live food source for fish fry, small fish species, and filter feeders. These organisms thrive in established aquariums, naturally reproducing to provide a continuous food supply while improving water quality through their filtering action. Daphnia are rich in proteins and essential nutrients, promoting vibrant coloration and robust growth in your aquatic inhabitants. Ideal for both freshwater and brackish setups, they're a sustainable alternative to processed foods.
