    Unknown Tube Worm in tank

    Ok these calcerous tube worms have been in my tank for awhile, i'm not sure what they are, but i haven't removed them because i actually witnessed one of them eating the hair algae, but lately they've been spewing out these long white threads that blanket my rocks, then the retract the threads and eat whatevers caught in them, anyone have any idea what these are ????

    I was actually going to put the same sort of question up. I have dam near the same thing in my tank. I think I read a thread a while back about them and someone saying to cut them off with a pair of side cutters. But you have to be fast becuase they retract themselves back into the rock from with the tube is comming out of. Don't know if i'm right.Any info would be great!!! Mine look like white tubes that comming out of the rock and they do the same thing as Fishmonger's do. They cover the rock/corals with a "web" looking stuff.
    Cheers,

    According to Dr Ron (if you want to get rid of them, as you probably do):
    "The only potential predators that I know of that might be able to eat them would be some of the larger hermit crabs or other crabs, or some of the whelks. And all of these animals cause problems of their own in reef tanks."
    and...
    "My guess is some crabs eat them, probably Banded Coral Shrimp would eat them, and some fish may eat them (but I don't know which ones specifically)."
    also...
    "Perhaps a 6-line or other wrasse may do the job."
    He also mentions Copperband Butterflies as a possibility.

    This was already covered twice just a couple weeks ago. They are indeed Vermittid snails. Nothing we keep in a reeftank will go after them, not even a Banded coral shrimp, Copperband, crabs, etc... They have a trapdoor that they shut as they retract quickly, so unless you destroy the tube by smashing it with a pair of pliers or cutters, the only other thing you can do si inject them with a needle but wuickly before they retract. They multiply very fast and cover everything with that web. The mucous web is used to filter catch foodstuff out of the watercolumn, then they retract it and consume it. If you have a few, I would start removing them soon as you will only get more and more.
    here's a link to one of the two recent threads. They start the 4th post down.
