I tend to doubt this theory, as eggs are collected from water that is often too
saline for much of anything else above the algal stage to survive. [Salt-water
hydra are called sea anemones, BTW. :-)] AFAIK, the young of FW hydra can't
withstand the extreme dessication, refrigeration and other processes the eggs go
through, either.

Simple to test. Put some in salt water at a SG of about 1.035-1.04 and see if
they survive. If they do, dry the container in a frost-free refrigerator, and
see if they come back when rehydrated and fed pure paramecia or other live foods
like that.

Nets, plants, filters, other live foods (daphnia, worms, etc.) and even with the
fish, possibly. They cling to *anything* that has been in another tank, like
thermometers, suction cups, air lines, etc.
