What in the world is this?!

[RussC]

I first noticed the tunnels on my rock about two days ago. They looked to be made of substrate. Kind of like you see if a mole or something moves under the dirt, but these were on top of the rock and white. Then this morning there are long worms extending from those burrows! The worms look like about 6 lb monofilament fishing line. Check out the pictures. I drew an arrow pointing to the worms and the burrows as well as a line showing you how far the worms extend up the rock from where they burrows start. They were at least 8" away from the burrow. What in the world are these things? This is a new one on me.

A google image search with 'tube worm' as my header (because lets be real, its a tube with a worm coming out of it) came back with a lot of things that don't look like what you showed, but one that does is pictures of 'vermetid worms' or sometimes called snails.

I don't know what they are, but you tell me if this is what you see when you google it!

Also looks like it might be called a 'thread worm'.

This is a very good picture of the same thing. This worm even built the tube out of the same type substrate I have. Looks like this is it. Now I just need to ID it.

Thats a very common and harmless/beneficial Spionid worm..

McG, one day I'm gonna stump you with one of my questions! Besides, what's an old veteran like you doing up this early?

Thanks for that website. I did not have that.

One thing I read said Spionid worms have two, short tentacles, less than 3" Is that accurate? Because these bad boys have worm like tentacles at least 6-8". There were at least two, but I'd need to count to be sure how many I saw. I guess they could grow just like anything else.

And the tubes of these worms runs along the rock on the top and bottom for several inches. It does not protrude vertically away from the rock.

I have about 20 of these in my 30. Most of them have 2 tentacles I've noticed that come out pretty far. At least 8 inches or so. They're cool as heck to watch

Vermetid. Harmless detrivore.

They don't seem to irritate anything in your tank?

A vermetid snail is a different type of creature..

Bring it on.. I welcome the challenge..
And since you asked... I get up around 6AM EST every day and hit up this site while on the toilet doing my morning business :lmao:

Based on the picture (from what I can see on my phone )

If the tube is hard - vermetid
If the tube is soft - polychaete

OMG. That image is burning my mind! So glad I'm all up in your morning business. :spin1:

McG, don't let me interrupt your meeting with a man about a dog this morning...

Last night my critter was busy. If I didn't know any better, this thing is intentionally building a tunnel-bridge to the neighboring rock. The tunnel increased a good half inch.

The blue arrows are the length of the tunnel over the last three days. The red arrows indicate just last night's construction. I did only see two 'worms' coming out of this tunnel. They are quick to retreat once we start turning on lights in the house.

 

[mcgyvr]

Yep.. Thats basically what they do..
I've had tons of them in every tank I've ever had..

 

[TokiHacker]

It's SUPERMAN!

 

[Betaktical]

Not vermetid. Spaghetti worm more likely. I have a million of them and they are actually pretty cool to watch. They don't sting or harm anything and are a sign of a healthy functioning tank. I have one that extends about 8" when he really wants food.

Nope. And they're literally next to just about every coral in there. Every coral is fully extended usually
