I wish I could help, but I have the same problem. If they get bad I pick them off with some micro forceps, but usually they pop up again before too long. If anyone knows of something that eats or controls them I'd love to hear it.

dremel, bone cutters, heavy duty razor blade, drill bit and screwdriver....whatever tool that fits that allows you to remove the rock completely out from underneath them, so that no parts of them remain

Ive had systems running that even though present,they dont really do much harm, and others where they go nuts and cause problems with nothing I can identify as to why

but they can surely suck sometimes, and if you have a bad case of them they can take a little work/maintenance

If you cannot physically remove them you can use a little kalk/Mrs. Wag's pickling lime but you have to be careful not to hit the zoas.

You can also superglue over them.

Hitting them with boiling RO water in a syringe worked for me. They do have to be open, and it is a good idea to modify the current so that it is flowing away from the zoa's and towards the hydroids if possible.

The ones I have, like in the photo, grow right on the polyps themselves, so all of those options are pretty much out of the question. Maybe a quick FW dip or something, assuming the hydroids would be more sensitive than the zoas given their smaller size.

They have a rhizoid like creeping stalk that is thinner than a hair, and clear. If you can get it with ultra fine (Dumont style) tweezers, you can peel several off at once. If you grab at the heads they just pop off and float away to start more colonies.

Of anything I get looks like hydroids I remove it before it goes in the tank. I have even passed on really nice drags because they are on them.

They stink. I know 2 people who completly started over because of them. Cook the rock and remove them from all frags then put the rock back in.
