Help with ID

It is living in a bunch of about 15-20 straw looking stalks. The stalks are brown, with orange fuzzy animals coming out of them

That is not necessarily and ID to just hydroids, they could be colonial tube worms or phoronid worms based on that. Some of them are quite small like these;

 

OOp's forgot the image

 

well i think we found the ID. right now i have a FOWLR set up, but would like to get some easier corals to start off with sooner not later, so ill keep and eye on the little guys and see what i can do. will they spead throughout the whole tank or will they stay on the rock. i have blue hermits that are kinda eating them. i am having a hard time making the ID confermed because they are taking awhile for all of them to come out of the tubs. but there are about 6 or so out, and they are little fuzzy light orange duster looking things. and about the picture, that is about as good as it gets. my camera fuzzes out when i zoom in any further. so i will just look at the great links you gave me and determin what they are. thanks alot, now i know not all little fuzzy things are cool, lol.

 

The worms I posted, yes, they often spread in large numbers, often to the point where you want tp rip them out, they are everywhere. Their tubes are very small. That pic I posted = 1/3 " long of all these dusters but some species get bigger.

 

A better picture tube worm

 

they might be cluster dusters small featherworms that come on live rock!

 

I agree with mannyhernz, sorry, I meant featherduster not tube worm. Are they concinder the same?

 

Yes, they are the same, well kinda. All feather dusters are tube worms but no all tube worms are feather dusters but all of them are bristle worms or polychaetes. The image I posted are more or less called "cluster dusters", still feather dusters of the Serpulid group, calcareous tube worms. That particular pic is a kinda rare species. It is a ref pic, to show what the unknown pic may be. I could have used other examples, to include phoronid worms, which are not worms or even related to worms all but called "worms", due to the lack of a better term

Also, lets not get all carried away that they are feather duster or some other kind of worm. There are some odd ball inverts out there. We need a better pic.

 

looks like some sort of algae to me!

 

Update

well I have kinda came to the conclusion that they are some kind of feather worm. They do a funny thing though. When I first turn the lights on, or well the daylights on, they start turning a light orange color, and stay this way most of the day. But about 2 hours before the daylights go off they start to turn a clear/white color. I don't know if feather worms can do this. But I know they are not a polyp now, or any kind of coral. They have one feathery layer of uncountable tentacles, and live in brown/clear tubs which they can retract into if they are scared or I turn the lights off. I think they are growing, but not spreading. Just thought I would give and update if anyone cares. Thanks for looking,

PS: still not able to get a better pic. when I zoom in to get a better look my camera turns to fuzz, so im just outta luck
