It is quite clear that most people and reference books feel
that hydra in tanks with adult fish is not a problem at all.

Now, concerning breeding tanks with fry, I am curious to
understand the extent of the problem. I do see hydra come
and go in my apisto breeding tanks, but I never noticed any
substantial impact on the number of fry, and I never read of
any actual report either. It may be that  I
just did not notice it, but I also wonder if indeed it is really
such a big deal. If BBS stimulates the multiplication of hydra,
wouldn't BBS also be the most easy and common food taken
by these freshwater anemones?

I would be very interested in knowing of any first-hand reports of
people that actually lost a substantial portion of their own tank
spawns due to hydra. Anybody on this list?

I am asking this because in my opinion medications should be
used only to solve problems bigger than those created by the
medications themselves. To treat for a remote or theoretical
chance may not be worth it.
