Please help ID worm

[HarryC]

This white worm in the second two pictures is only on the skeleton of one acanthophyllia. It has tunneled into the coral skeleton and also has sand tunnels wrapping around the skeleton that I've found almost daily. They are only on the one meat coral. I have two other meats that have yielded no worms through dipping while this specimen continues to have these coming out the past three days. I have been dipping in Bayer followed by Iodide. Alot of people seem to think these are a type of bristle worm so I included a picture with my typical bristle

Not sure of the white but the red ones are bristle worms.

I included the regular bristle worms because people really think the white are also a bristle. The tunneling into the skeleton and sand tunnel behavior is why I'm questioning that, although I know there are a lot of different bristles.

This acanthophyllia is the newest addition to my tank. These worms seem to have survived my initial dipping regimens (coral RX, Bayer, iodide all for 10 min with a powerhead) , but I'm really hoping are only in the skeleton of this coral.

Does it look like a fireworm maybe?

 

[HarryC]

I personally think it looks like some sort of Eunicida but am far from an expert I've only been able to use Google and asking local friends for help. Was hoping someone on here had come across them

The individuals that I tagged are experts. They will have an answer for you.

Thanks very much man. If I continue to find them over the next few days I'm gonna start to get really worried. Was pretty shocked more worms came out today when I dipped ( day 3 ) I noticed something was up because the meat coral wasn't fully extending. It seems to be happier now that I'm removing these. I'm doing a tank transfer in the next couple weeks so if this is something really bad I'll take special precautions and do some extra dips on my other LPS.

 

[HarryC]

also how weird are the little poop/eggs coming out of this monstrosity?! The first one has been alive in a tiny cup next to my tank for 4 days.

Your welcome.

I've only been reefing a year and I knew at some point I was gonna encounter more than Aiptasia! These things seem to have a lot of people stumped. Tomorrow when I dip again I'll get pictures of the holes in the coral skleton they're coming out of.

I've so far gotten fireworm, peanut worm, bristleworm, bobbit worm, medusa, damaged feathe duster as Id's haha so at this point I'm not ruling anything out. They're clearly segmented so not peanut. Have a visible mouth but no visible pincers so im unsure on Eunicida... trying to ID these has me thinking about the endless possibilities we face for hitchhikers

 

[HarryC]

I think I've found them! Sigalionidae is the lead suspect.

 

[reef lover]

I lean toward syllidae...remove.

 

[kireek]

Don't know what you have there. I would throw it out.

 

[HarryC]

I'm throwing them out but they seem to find their way back into the acanthophyllia nightly. I set a worm trap last night and only caught regular bristles. Getting ready to dip the acanthophyllia for the fourth day in a row will report back.
