Hi Sean,
While I can see the benefit of having utrics in a breeding tank to
provide cover for the fry, the Daphnia part sounds strange. I was always
under the impression that Daphnia are a favorite menu item for these
plants. On the other hand there are some symbiotic rotifers that make
their homes inside the traps of some species - hmmm. I wonder if the
aquarium reference has the species reversed.
FWIW
