Moina are primarily found in ponds or ditches. The males are smaller than females and the period to reach reproductive maturity takes four to five days at 26 degrees Celsius.

Copepods are a group of small crustaceans found in the sea and nearly every freshwater habitat. Some species are planktonic (drifting in sea waters) and some are benthic (living on the ocean floor), while some may live in wet terrestrial places such as swamps, under leaf fall in wet forests, bogs, springs, ponds, damp moss or water-filled recesses of plants. Copepods are sometimes used as bioindicators.
