steveweast - I recently found a smaller version of your worm(s) in my tank, and this is after a long time of searching for the predator that ate every orange zoanthid polyp of the very first coral colony I ever bought. By chance I saw the iridescent black body sliding by a rock crevice a couple hours after the lights went out. I have no idea which rock it calls home, or how to figure this out. I remember seeing a tiny cool black worm in the base rock of an acro frag, and I wish i knew then what I know now. I could've nipped the problem in the bud before it grew its appetite! Any suggestions?
 
There's no quick way to tell which rock is home.......you just have to keep viewing over several nights and a pattern of his movements will be noticed. I observed mine over about 8 nights to determine with some confidence the correct rock. As the worm get larger, the tail always stays in the lair while the head goes foraging......the head always then recoils back to home base.
 
Are there any telltale signs at the entrance of their hole? And is it more likely that it'll open to the inside of the rockwork? I haven't been able to see this guy before or since my recent sighting, and it didn't even seem to bother with the trap I made. I'm just looking for pointers to make my searching a bit easier.

By the way, I don't mean to hijack this thread, so don't hesitate to pull it back on track.
 
Sorry....no telltale sign. They do have "rabbit pellet" looking droppings though.......but, that won't tell you where home is. Unfortuneatly, you have to just keep looking and remove him with his rock home. I've never had, nor I have heard of anyone having, any success with a trap.

As for the eeewww factor....remember, these things are considered good eats in Fiji.....or at least their tails are....which break off and swim to the surface to release their eggs/sperm. The lesson....read those menus carefully when travelling in Fiji.


a nice head shot.....

HOLY COW!! Do those things bite? B/C if they do I've got a few neighbor kids I'd like to get rid of......

No, but seriously, do they bite?
 
yes they bite, you stay like with a small irritation.
I ve always heard to remove them, because when they grow they will get into the PVC and you can have your room plenty of water !
 
ok.... now that i've lost my appitite by looking at all these 3'+ worms...

i'm skipping dinner and keeping my eyes pealed to my tank tonight!!!
 
hay i dont have worms in my tank so I dont know if this will work or it may have already been thought of but you might be able to observe them with a red light(most animals cant see it dunno about invertibrates though). It would be a cool thing to have in a species tank though
 
Lol .... come on guys they are just worms...

I've pulled out 5 of them from my Fiji live rock. I also had one before in rock i bought from TBS so it's not just Fiji rock that carries them.
 
steveweast Wow i thought I was the only one who ever had there ricordia chowed on by these things. He would come out at night and eat the inside of my ricordia leaving a hollowed out center so the polyps looked like a spare tire. After losing half my rics i decided to break down the tank & to my surprise while hosing out the old sand out crawled & little one only 12in but boy what a pain in the butt. My ricordia are now making a come back.
