Strange worm, almost looked like filter feeder/alien lol please ID

[CierraBeckwith]

I was watching my rock flower nems (because I keep hoping for spawning) and saw this thing, i thought it was one of my brittle starfish at first, but you can see one of the starfish legs above it so I know it's not that. Plus it moved like a worm? And like folded into itself, also it almost looked like it had a filter feeding part come out the top of it?? I hope it's not a bad guy cuz it disappeared quick at any sign of light.

Any photos?

It is really hard to tell from that description. You could try to take a look at common hitchhiker worm photos and see if anything looks like what you saw. Bristle worms, peanut worms, spaghetti worms, flatworms, etc.

That's a strange one. Definitely not a brittle star. @ISpeakForTheSeas any ideas on this one? It is a bit fuzzy, but the end seems to fan out at times. Could this be a species of Clymenella? Another spike-funnel-anus worm?

I would have expected it in the substrate though.

OP, do you have a sand bed?

Interesting, an unusual one. Sort of reminds me of the trunk of a conch, but longer than I've seen one.

It's possible that it's from that family, but I'm leaning toward it being a peanut worm like below:

Phascolosoma (Phascolosoma) agassizii Pacific Peanut Worm, Agassiz'z peanut worm

Phascolosoma (Phascolosoma) agassiziiis commonly referred to as Pacific Peanut Worm, Agassiz'z peanut worm. Difficulty in the aquarium: There are no reports available yet that this animal has already been kept in captivity successfully. Toxicity: Toxic hazard unknown.

The funnel-ish part on the one in this pic look's similar to what I saw, but the colors are different, but I do have a sand bed, where I saw this thing at was in my rocks, maybe 4-5 inches above the sand bed.

Okay it definitely looked more like a peanut worm! I hope there not bad because I doubt I will be able to catch it. It was the first time I have even seen it. lol

They're harmless/beneficial (good guys for the tank).
