[MyNameIsJoe]

Found this worm when I pulled some live rock outa my tank. Anybody know what type of worm this is and is it good or bad?

tanks....

Looks like a bristleworm. Unless they grow huge, they are usually a good thing to have in your tank.

It could be some species of Ribbon Worm, or some species of phyllodocids. Doesn't look too much like a bristle worm if you ask me.

No it is not a nemertean, it is a little bristle worm that are quite common and are very beneficial member of the detritivore guild. I would put it back in the tank, Joe. ;)

rluix, what made you think it is a nemertean or a member of the phylodocid group?

Just because I didn't think it was a bristtle worm, and there are some worms from these species i mentioned that looked like it.

Joe, when it's full grown it will look like this:



Yours is at least a couple of months away from reaching this size.

Thanks everybody. I have seen bristle worms before, but what threw me off was the orange outline on this one. back in the tank it goes...

Did you see the "bristle worm" eat it while it was alive or after it was already dead?

Do you have any photos of your "8-10in bristle worm?" There are several thousand different worms that can be called bristleworms, so it helps if you can narrow down your description a little. If it is a common Eurythoe complanata, then it shouldn't cause any problems. However, there are quite a few "bristleworms" that can cause problems, so it's impossible to comment one way or the other without knowing what we're talking about here.
