Beverly's thought above reminded me that some years ago I won a packet of a
new food product to be added to homemade fish foods. It was supposed to
include all sorts of Omega3's etc. etc. and to gel the liquid parts of the
food so water quality would be protected. I added a little of it to some of
my daphnia food as an experiment. The Daphnia stuck together. Beverly could
have hit on the cause if it is not metals or chemicals.
