Aptsia(sp?), feather duster, or something else ? (pic's included)

Could some one please tell me what this red stuff on the rock is like ? It has a red stem, then small thin grey like line's growing out of it.

Hmmmmmmmm I'm not to sure on this one.

im not a 100% sure but i think it is a form of macro algae that is red. its definetly not aptasia, or a anemone. dont quote me though on the alae. i had it in my tank also.

I have lots of it too, but have no clue what it is!

It is not aptasia or a feather duster. From what i can see from the pic it is probably either a red macroalgae or a sponge. With a closer shot it could probably be identified. If those three central stalks have tubular openings in them, it is probably a sponge. If it is plantlike (for lack of a better term) it is probably a macroalgae. Whatever it is, leave it alone, as it is not detrimental. Just one of the reasons live rock is so great.

Their foraminiferans, harmless filter feeders.

Thank's
From your description/explanation, it seem's to be a sponge. I could take it out and take a better shot if needed.

Don't take it out!!! Sponges do not fair well after being exposed to air. If they survive the shipment on liverock and setlle into your tank leave them alone. As I said whatever it is it is harmless and will probably continue growing. Good luck and enjoy... sponges are neat

Thank's. I don't plan on taking it out. i've got a few rock's growing sponge's on it. Hopefully by Jan, i will have more stuff come up in the tank

NACL H20 is 100 % correct and I concur- go with what he says on this.

I have the same thing isnt it GREAT!!. I think it looks neat. I found a really neat slide show that shows alot of the macro algae. I found it in the search, on this forum. Just type in algae slide show, under search, I think you will find the same thing there.
