Worm like hitchhicker

[pelena]

I think its a tiger tail or similar. It is lighter than the one in the picture and has a few bands. Doesn't seen to have tube feet, it stretches out to climb. Doesn't seem to be able to climb the glass. Seen it as small as 1.5in and streched to 5in. About pinky width in girth. Any body got info?

The picture is definately a sea cucumber. However, all cucumbers have tube feet, so if yours does not, it is not a cucumber.
It is possibly a bristleworm.

the one in the pic is not mine, i got it off a web site for comparison. I'll try to get a pic of mine, but it found a spot and hasn't come out lately. it has a short whiteish fan that comes out of its "mouth" like black cucumbers have.

I've got something that looks a lot like that in my tank.
After asking on hear and looking through pictures and comparing it to what I had, I found out that it was a bristle worm...
They look a lot like the picture of the cucumber...

Does the thing that comes out of its mouth look like big tube feet with snowflake-shaped tips? Are you sure it doesn't have tube feet under its body? If it is a sea cucumber, they will generally stay around the base of your liverock in the shade, or hide altogether when the lights are on. Does it poop out sand?

I looked up some bristleworms and it deffinatly doesn't look like any of those I saw.

this is a picture of mine. It was on top of my powerhead and I knocked it off to get a good shot.
