Subject: Daphnia
For years I have been told the benefits of live daphnia as a food for
freshwater fishes (beginning with my reading of Innes' Exotic Tropical Fish
nearly 40 years ago as a kid). I was recently reminded of this during an
outbreak of green water. Although I didn't try it (I cleared the tank with
a diatom filter), some suggested that I introduce live daphnia as a algae
control measure. I've seen freeze-dried daphnia in the LFS but never live.
Can anyone enlighten myself and others on how one goes about securing and/or
raising live daphnia? I would think that daphnia strained from local
streams and ponds would be risky in terms of introducing unwanted parasites.
I have been using Daphnia I collect myself for around 30 years now and have
never had a problem with it. I usually collect it from the local park which
has a lot of ducks on the lake which with all there poop feed it and it is
in large clouds especially visible on a sunny day. If you are worried about
unwanted parasites which you may introduce then freeze it into small slabs
in plastic lunch bags and break off and thaw what you need for each feed. Go
for it and your fish will never look back,especially rainbow's.
