Daphnia pulex is the most common species of the water flea, an organism which can be found in almost every permanent, eutrophic (nutrient-rich) water body. A few species are marine, but generally Daphnia , including Daphnia pulex , are freshwater organisms. But Daphnia are declining in Lake Superior and nearly every other body of water in the Great Lakes region.Their numbers have been decimated by a fierce invasive predator, the spiny water flea Culture water should be 18-20°C for daphnia and 24-31°C for moina. Position the light over the vessels and set on a 12- to 20-hour photoperiod. Maintain a pH of 6.5 to 9.5. Keep ammonia concentrations below 0.2 mg/L.
