Hydroids? Need help!

[HolyMackrel]

Long tube with "hairs" sticking out all over. They look like several types of hydroids I found in the forum, but seem slightly different. From what I can see, they are covering the rock in areas of high flow and and a few zoa frags. Zoa's are agitated and haven't opened fully in days.

Disregard the spirorbids, they are everywhere.

Just realized zoa pic isn't helpful. The critters in the top pic are all over the zoa

I have them and can’t get rid of them for nothing but my zoas seem to not be bothered
