ID worm coming out of rock

[stanleo]

I can only see them at night. There is one living among the GSP but I can't get a decent pic of it. They seem to search for floating particulate matter. Doesn't seem to both the coral. There are several and not all of them are this thick and some are white and super long. Any one?

Interesting.

I thought peanut worm at first myself and this one could be that but I was researching further and found literature in Advanced Aquarist about Hydroids - Candelabrum spp aka digitate hydroids and I think that's what the white long ones might be. Especially the one living in the GSP. They go after pods both in the water column and crawling on rock work. I have no idea how to get rid of them.
