Type of worm?

[Rich 9_70]

Hello Everyone,

I just brought home a green bubble coral colony from the LFS, dipped with Koral MD and a bit of Melafix. Four of these worms came off.

Common bristle worm or something more nefarious?

Hard to see the antennae in these pics, but looks like they are curving backwards, so could be a Dorvilleidae. Harmless, I understand, even though a bit freaky (very active swimmers when they go into the water column). Do you see 4 antennae?

Some kind of Polychaete. It may be a medusa worm based on what I think I am seeing on the head.

Yes, looked like four antennae coming off the head. Thank you for the quick reply!

Hmm, Googled images of the Medusa Worm…could be them, hard to tell, they are super small. But what I read, either way they are most likely harmless. Thanks for the insight.

I don't think it's a Medusa. They aren't polychaete worms, and the antennae go every which way. My bet is Dorvilleidae. I'd still toss them, but not the end of the world if they get into your DT.

I am curious to see what Erin has to say. Can you get any more pics or are they already gone?

I have already tossed them.

I have already tossed them.

I assumed that would be the case after a dip.
