Hydra in shrimp tank

[vince82]

Never had hydra before. I read it's relatively harmless, should I treat with No Planaria? I read it's effective against it (bonus points for also removing snails).
This is a 2.5 gallons cube with blue diamond neocaridina

They WILL kill baby shrimp.

Gneiss rock in the middle of the tank. Did you collect that yourself?

Of all the rocks I have in all my tanks, that is the only one I bought in an aquarium shop

Too bad, it is a nice rock. I would have been proud to have collected it.
