What is growing in my sand?

[Alex 26.2]

These little things have been in my sand for around 2 months, at first I thought it was just detritus and when I tried to vacuum them I found they go deep into the sand bed! Part of them sticks out of the sand but 3/4 of them are in the sand it kind of looks like roots. Just wondering if anyone knows what they are?

Thanks!

Do you ever see anything coming out of those tubes? Two little antenna looking things? My guess would be spinoid worms.

I've never seen anything coming out of them before, I looked up spionid worms and they don't have those two antenna type things. They don't really look like they are some kind of tubes either.

Here's a picture of what I think they might be. Maybe not though.

Resurrecting this to see if anyone knows now.

You sure nothing comes out of them? At all? What color are they?

 

[Airborne12B]

I can't speak for the OP, but I'm positive nothing comes out. They look like vertical fish turds jammed into the sand.

You absolutely positively sure? Sometimes the tentacles can be barely visible

Absolutely 100% beyond a shadow of a doubt sure there isn't anything coming out. I've spend hours with my face to the glass watching them.

Take a peak early in the morning when the lights are out.

They're under the top layer of the sand-bed, and I can only see them if I vacuum up some sand during a WC, but I will uncover some tonight to watch in the morning.

What are snail worms? Internet images reveal a snail beside a worm, possibly the snail wants to eat it.

Like vermetids?

Thats interesting. But as Alex said, nothing comes put of them. Might be some kind of macroalgae

Have you tried grabbing a tube with a pair of tweezers and pulling it out of the sand and putting it in a small dish so you can inspect it and even cut it open?
