I never noticed any discomfort in my fish, but the green hydra I had
to deal with stayed pretty small. The largest I ever saw was just
over 1/4" (6mm) including its tentacles. I suspect my regular use of
a diatom filter at the time kept their food supply limited, and they
died off after a few months. I've heard of hydras as long as 1/2"
(13mm) minus the tentacles, so it's not hard to believe they could
cause trouble.

The biggest concern i've ever heard for hydra problems usually occures in
breeding situations. A colony of hydra can wipe out an entire batch
(several hundred) early freeswimming young fish. Have heard stories
talking to a few local breeders about this happening in the past after
reading an article on it in the club magazine.
