ID a couple of things

[Floyd R Turbo]

I found 2 of these in the tank today. I think they're bristleworms, I've found one before, but it was a while ago. The first one here has not hardly moved from this spot in days:

It's coiled up on the rock, just above the center of the pic.

The second one I just spotted today. Harder to see, look in the "V" or "W" formed by the fuzzy mushroom and the red cap.

The second thing I noticed, I have no idea what this is. It looks like a large tube worm or something. There are dozens of mini-feather dusters in this tank, and this looks like one of those except 10x bigger.

Anyone?

That thing in your first picture... it's not a bristleworm. I have one just like that in my tank too. Doesn't ever move very far from "home" and usually hides itself in the nook/crannies of the rockwork. I have absolutely no idea what it is though... except that it isn't a bristleworm!

Yeah, I've been searching for what it is, can't seem to find anything else that looks like it. What about the 3rd & 4th pics? Looks similar in structure to a Tube Anemone but I've never seen it "out"...

These Animals are Serpulorbis sp. Don't Know the english Common Name.

hard to tell from the pics, but it's not a common bristleworm. check this page out and see if you can spot it-

I have lots of them. They can multiply very quick. I don't like them Cause some of them can make webs what especially SPS corals don't like. I would suggest to watch them and react if necessary. They have a Long body like a worm and can close their top hole.
