Coral? Critter? Issue?

[SaltySquid]

Ok so I have no clue what these things are. I have a single head to one of my flower pots growing in this rock and now I have these other things growing near it and on other areas of this rock. It's not baby heads of the coral, didn't react when I squirted them with Aptasia Ridex....what are they and are they bad? They are hard to see under white lights but if you look at the base of the flower pot on the right side you can see one circular head with whiskers/tentacles (idk) that grow on a stalk and two more just above it. It almost looks like one of my ZOAs but it has a stalk and they are in small groups of 1 -3, plus a good 1-2 feet away from the nearest one

Colonial hydroids.

 

[SaltySquid]

awsome and from what I've gathered so far this is no way to get rid of them. Is my Nano tank doomed to perish?

 

[KJ]

Did this hydroids show up just on one rock or spread all over?

That is not a Goniopora, it's either Clavularia/Clove or Tubipora musica.

Nope the tank is not doomed.

Does not look like hydroids. I agree with the above post, clove polyp.

It appears to only be on one rock from what I can see at the moment.
