ID Critter please

[killerinstinct]

Hello I dipped some zoas in Bright-well Aquatics Koral MD cause I found some tiny critters on the rock of the zoas. Not sure what type of pest these are or how to get red of them since the dip did not kill them. Can you help me ID these pest. They have a pair of white antennas. Also found them in some Sps of mine as well.

I don't see anything in the picture, but based off of what you described them, they could be copepods.

They look like this:

Could be spionid worms. Do they quickly retract when you touch them? If they are spionids they are incredibly difficult to get rid of.

They do retract fast, when I dipped the rock they retracted and came out 3 min later in my tank

They look like this:

If you zoom in the rock outlining(edges) there’s little antennas all around the rock

How can I get rid of them?

Yeah, those are not copepods.

It thought that was just some GHA.

Yeah, those are coral-boring spionid worms; it looks like yours are already booming in population, which is really unfortunate:

Those have a tube like outer and inside they pop out with the antennas sticking out. I don't know the name of them but I had them on some frags I got and I killed the 6 or 7 by just taking the whole coral off the plug or if it was a rock that a mushroom was sitting on I glue the whole rock and now I don't have any left they are all dead.
