What are these?

They have grown 3 or 4 millimeters in the last few weeks. The coral is a blastomussa merletti.

Could be vermetid snail or tube worms. If seen throwing out web like strings, vermetids. If it's those, remove them manually.

Looks like a scary hand lol.. I would also recommend removing. Make sure you get it deep not just breaking it off. Vermetids live deep

Dang it. There is one in the acans too. Growing right out of the freakin middle of the coral. I’m afraid to mess with it.

Take a pair of tweezers and snap it off.

The one in the scan was a centimeter long. Only a quarter of it was visible from looking at it.

does it retract at all when disturbed?

 

[joshwaggs]

Not at all. I still don’t know what they were. They didn’t send out anything, but they also didn’t have little feather duster type things that came out. They definitely look like some kind of feather duster structure, though.

The white speck. Checked the link

But nothing matches.

I think they are snail eggs.
