Hi all. No idea what this is.
Thanks for the help.

Looks like a feather duster worm with some xenia growing on it.

 

[USMC4Life]

Thought the the same at first. But the worm had two antennas looking things sticking out and then it produces a mucous membrane that catches its food and sucks with back in.

Looks like a big vermetid to me, perhaps growing on a feather duster casting

 

[Sharkbait19]

Yeah, sounds like a vermatid.

 

[fragit]

Looks like a feather duster that blew its skirt

 

[JGT]

Spionid worm.

Are they bad ?

Are they bad ?

Lot of reefers break them off or cover with superglue because of belief vermetids can irritate corals.

that thing is huge, get it outta there before it makes more

Not too dangerous, but a pain. They shoot out a mucus net that irritates corals and keeps them from opening up. Break it off at the base and crush it out of water. Or glue over the hole if you can’t get the whole thing off.

keep it, it is a vermetus vermetid, the huge ones don't seem to usually breed in captivity nor irritate as much corals

It had a hard tube. It started to spit out a web of slime. I ended up getting rid of it.

it's been there 2 years and you never had issue with it, it could be there 10 more and you'd still not have an issue
