Daphnia- Also know as water fleas, these tiny water insects (Daphnia pulex & D.
magna spp.) are great natural food for any small to medium sized fish. They can be very
tiny to an 1/8 of an inch or so. They can easily live in your tank for long periods if uneaten.
A starter culture is need to start a colony.
Daphnia can be cultured in any size container. We use 10 gallon tanks and one gallon
jars to raise our daphnia. The easiest way to jeep a daphnia culture going is to use aged
green water or heavily aglaed water. Aged aquarium water with just a bit of aquatic or
non-aquatic plant fertilizer can be left in full sun for a week to get green/algaed water.
Daphnia eat the infusoria and other microorganisms which grow in such water. You can
also feed your mother daphnia cultures dried brewer’s yeast, powdered milk, pumpkin
pulp, or squash pulp. Avoid vigorous aeration of the culture.
Hatchery tanks can be seeded with Daphnia -- the Daphnia will continue to eat bacteria
any other microorganisms that may be present. Daphnia generally purify water and the
fry will eat them as they grow to sufficient size.
A shrimp net or a fine fish net can be used to catch Daphnia. Invert the net to feed.
Over feeding of daphnia is almost never happens, but over feeding in a tank with heavy
filtration might lead to problems if the daphnia die off quicker than they are eaten.
