Small white (?) worm

[banghair]

Was just staring at my tank and saw a really small worm, maybe a centimetre in size, it looks white, maybe gray, and it was moving fast. Only saw it for a few seconds.

I first saw it on my live rock, then it went on top of the sand and I lost it.

I have 5 corals, 5 hermits, 3 shrimp and 7 snails. Should I be worried? What steps should I take?


I’m planning on adding clownfish on the 24th (6 weeks after a brook issue), should I hold off?

edited to add: it moved like a snake or earth worm

second edit: it looks striped now that i’ve been able to see it longer, tried to capture picture and video as well, thought it’s a bit hard.

Pics under white lights are very helpful in a situation like this as it can be several types such as epitoke, dorvillidae or others

it was ridiculously small, my camera wouldn’t have picked it up. i almost mistook it for hair algae.

Probably an epitoke

Just found another one, they are hanging out on the rock, not sure if this video will work or is even good enough.

Love the sexy shrimp!!
The worm looks like a detritivore, although I can't tell for sure. As far as I know, small worms aren't usually bad to have.

@ISpeakForTheSeas might have a more knowledgeable answer though.

Thanks for the tag! I have finally gotten around to starting learning about marine worms, but I've got a long ways to go still (worms are surprisingly diverse and complex).

The video is pretty blurry for me, but I can't see any chaetae (the "bristles" on bristle worms), which are usually pretty prominent on predatory worms. The snake-like motion eliminates a lot of other bad actor worms, so that was a good inclusion. It might not be possible but a full length shot of the worm, and particularly a shot of the worm's head (especially if it has any noticeable tentacles or a unique mouth) may be helpful for ID.

That said, while I can't tell what kind of worm it is from what I've seen, I agree that it looks like a detritivore to me, not a predator or parasite.

Looks like a syllidae or Oenonid worm but from the distance in video, hard to confirm.
