Add Spixi Snails! I put a bunch in my shrimp setups because i had hydra and they ate every single one! Just my 2 cents!

In my experience, they died off as tanks matured, in a week or so.
And they never harmed my fish, including small tetras.

Try this, I plan on it, because I have hydra myself.

Mind, I expect the OPer has fixed it by now, what with it now being 2010.
