I've never had trouble with hydra before. So where do they first crop
up? In my 2.5g shrimp tank, with a female holding eggs! *mutter*
They must have come in on some plants I grabbed from outside.

I'd prefer not to move the shrimp. They're red cherry shrimp and very
sensitive to changes in water conditions. That means no copper or
fluke-tabs for the time being.

Putting a Hydra eater in the tank temporarily seems ideal, but I'm
afraid a Trichogaster spp. gourami would eat the shrimp right along
with the Hydra. I read on the Krib that mystery snails will eat Hydra.
Does anyone have any experience that agrees? Are mystery snails likely
to leave baby shrimp alone? Are there any other small, mild-mannered
hydra eating creatures?

From the Advanced Aquarist Guide, Dr.Ghadially
Hydra are rather particular about water conditions and temperature, and
can hence be destroyed in many ways: i) Raising the temperature to 105F
for 15 minutes after the removal of the fish, ii) Ammonium nitrate
method, 300mg/g, repeat after 4 days if required, iii) Quinine, chlorine,
formaldehyde, copper sulphate etc are all equally effective, though
needlessly drastic, iv) Gouramis, Paradise fish and pond snails are all
reported to eat Hydra. hth

Given the presence of Cherry shrimps (you don't like to make it easy, do
you??? ;~), how about a licorice or dwarf gourami?
