How would you like to cultivate and raise your own separate tank of Daphnia (also known as water fleas)? These tiny plankton-like freshwater crustaceans grow to about 3 millimeters in length or less.

They live quite happily in large groups within a tank, so that you can harvest them when you need them to feed your fish, tadpoles, salamanders, newts, or aquatic insects.
