'''''Daphnia pulex'',''' although often called water fleas, are freshwater crustaceans closely related to shrimp. Daphnia, the most common microscopic crustacean, can be visible to the naked eye, with lengths ranging from 0.2–5 mm. Their reproduction alternates between asexual and sexual reproduction, with females laying eggs during the warmer season and males only being produced during stressed conditions, such as overcrowding or cold temperatures. | '''''Daphnia pulex'',''' although often called water fleas, are freshwater crustaceans closely related to shrimp.

Unfourtanetly, the amount of the yeast caused the overfeeding for fleas. For the further process the amount of it must be less than before and the water clarity should be take into consediration to avoid overfeeding. | |||
