Hydroids on my lps HELP!

[Highweigh]

So I will soon be in the process of transferring over some corals to a new 40g breeder.

The corals are in a frag tank now with no fish or inverts.

I removed all the corals from rocks because they were starting to get overrun by hydroids.

However now I fear that some of my lps may have hydroids growing on their skeletons. I can see at least one hammer coral has one or two growing out of it.

What should I do about this? Can I dip the corals in something to get rid of these pest? Or what would the best plan of action be?

All help is appreciated.

This is what they look like

Hydroids are the devils spawn, eventually and after trying everything and nothing worked, including covering them with putty etc, I used a 4 spot and a pearlscale butterfly to get rid of mine in an sps tank, but not sure I'd be brave enough to put them in a tank of Acans

Your butterflies will leave your acans alone. If they don't then that sounds more like the acan's problem and less of yours.
