I. Hate. Worms.


I just kicked my powerheads into feeding mode to feed my tank. Seconds after the current died down, I noticed something I had noticed a couple times before, but this time something was different...

There was what I can only explain as "smoke" puffing out of a hole of a large piece of liverock. Something I've seen snails do as well... sperm (I'm guessing).

What was different about this, was the critter I saw when I leaned in to get a closer look. The head of this thing was probably 1/4 to 1/2 inch wide. I could only see the tip of it, but it was dark dark brown, and I could see 2 tentacles on either side. It looked a hell of a lot like the pictures I've seen of the GIant Reef Worms (Eunicid worm). GAAAHHHHH!!!!!

I may never stick my hands in this tank again. I'm tempted to completely remove the rock I saw it in, but I have 3 different kinds of SPS attached to it, not to mention a couple different kinds of zoa's.

I've been paranoid that there was one in my tank, because I've seen bits of light brown poo that looked just like a picture someone posted of this worm's feces. I wish I could find the photo again...

I'm 100% creeped out and a sliver of a decision away from pulling that rock out and busting it up to make sure I got this thing out.

Now... before I completely jump to conclusions... does anyone know if the Eunicid worm blows out puffs of (I'm calling it) "smoke" like that? I do have Stomatella varia snails in my tank... and there's a small chance I'm mistaking the two. I didn't have a great angle on what I was seeing.

Is it worth it to yank that rock and possibly kill three small SPS?

Also: If I dipped this entire rock in a bucket of RO water to kill and get this worm out (if that's what it is), would that be certain death for the corals?

Also also... would an Arrow Crab eventually eat a eunicid worm??

...AND... are these friggin things a-sexual!?!?! Please tell me I don't have more than one in my tank...

It's just a LITTLE worm.:toothy12:

Of course some can grow to 2 meters or bigger.
Eunicid Worm
Some will feed on some types of corals ( Bobbit worms )

Nothing to worry about :chicken: :nanananan
Well, I turned on my reds and camped in front of the tank. I'm glad to say that I saw the critter in question slowly come out of the hole after about an hour. It was a Stomatella snail thankfully.

I'm still a bit creeped out and leery... And wondering what the fairly decent sizes poo is that I see on the substrate.
