Acropora inhabitants

[Doh Boy]

Hello,
I was watching my acropora and I saw some movement on it and am curious as to what it may be. It looks to have antenna or something that hang out of a hole. The acropora seems unbothered by them. There are only two of them and then one with a long sweeper that goes in and out rather fast. I also caught the little creature crawling out partially.

They actually look like a copepod.

The ones in the OP’s pics are not vermatid snails, but vermatids can encroach close to acros and then the acro will eventually encrust over. Vermatids have a hard shell and the spionid worms have a spongy soft liner. The spionid are an eyesore but harmless. I’ve had vermatids irritate some corals and cause Stn

I thought about using a drop of thick CA to cover the hole on a couple of mine. Quite a few articles out there; here is one:

ID: Spionid worms? How do I get rid of them?

Hey guys/gals, I seem to have an issue going on in my reef. These tube worms are growing on my sps, not really irritating them but sure as heck being ugly. If I look really closely, there are 2 tiny antennae (or at least I think there are). They don’t have the feather structure of hyoids and do...

Do you have a pic of them? I usually just crush vermatids but I haven’t found anything for the spionids besides fragging
