Digitate hydroids and peppermint shrimp

[NanoReefLife]

I bought a peppermint shrimp in attempt to get rid of digitate hydroids based on others posts. Unfortunately i watched the digitate hydroid touch my peppermint shrimp and he jumped. So i dont think the peppermint shrimp will work.

If any one has had experience with this pest and got rid of it sucessfully how did you do it ?

I totally forgot that i did test on one of those hydroids. I put a digitate hydriod that was on a empty snail shell in a little tupper ware container with tank water. I then added coral revive to the water as reccomended. It took about twice the recommended time for dipping corals for the digitate hydroid to die.

It would be interesting to see the effect with either higher concentration with shorter duration or long duration with low concentration.

My theories for these are if the dip is for a short period of time then the dip wont be able to get absorbed into the rock very much. For the second idea if the concentration is low enough it might be at level the corals can tolerate for but the digitate hydroids will die with prolonged exposure.

Unfortunately i do not have a quarantine tank to try the second method.

Any ideas?
