Hydroids!

[Live Rock]

Hi everyone I have all around my tank stuff that looks like yellow polyps parazoanthus but are smaller. I am thinking that they are hydroids. What should I do to remove them? Are there any known predators of hydroids?

Thanks for any suggestions. :D

It's hard to know if what you have is hydroids or not without a pic.but if it is hydroids,then you've got 2 choices.
#1 is tossing all the rock that has hydroids on them.
#2 is trying to kill them using super glue gel.
But post a pic,then we'll figure something out weather its right or wrong.

BTW
I like that Crested in your avatar.Looks a lot like the little Buckskin I've got.
