Weird tentacles, could it be Aiptasia?

[ivandrago]

Happy Saturday girls and guys, can you please help me and take a look at the pictures that i have attached.
The first picture is my live rock that has been in the tank for about 5 months i have found some weird tentacles growing out of it to be exact three, on the picture you can only see 2 they are clear with black stripes i call them zebras.

The second picture is a combo rock that i bought from maximum reef aquatics, and it has some tenticles growing from under the polyps.

Is this Aiptasia?

the first pic looks like little brittle star tentacles and the other pics look like nudibranch tentacles. If you pick up the rock on the first pick, you may see the brittle star

I would dip that zoa if you can

 

[ReefFreak1]

Don't dip that. It looks like a type of worm that will start to build tubes out of your sand bed and eat crap off of it too. I have these clear tube worms all over and there's about two to four tentacles with each. All over my reef tank. Just part of the clean up crew.

A zoa eating nudibranch

Damn how do I get rid of this nudibranch
And the bristle star isn't comin out in the first pick is he just going to stay in the hole

 

[ivandrago]

I googled nudibranch and it doesn't look like it, it's more like just like hair follicles that are just sticking up an feeding on what flows in the water

 

[jdnumis]

You should be OK

I have those same things in my sand bed. I thought the worst as I usually do. They act as a clean up crew as per the previous post.

The top pic looks like aiptasia to me. Get rid of it quick before it takes over your tank. Aiptasia x will work on just a few. Beyond that check out one of the many threads on this topic

No Zoa eating nudi branch. All these tube worms do are clean your substrate.

 

[tunicata]

the top pic is a brittle star. i'd just leave it be.

the second i dont know.

 

[ivandrago]

great thanks

I've never seen my micro brittles sticking their arms straight like that, always like curved.

 

[ivandrago]

if you guys want i can try and take a video and post it but i doubt the forum will let me do that

 

[bizzarro]

Upload it to Youtube.

 

[ivandrago]

Reeffreek1 thanks you were right these are like tubes and they have the hair hanging straight up I made the polyps curle in and there it was a clear hard tube and the sucker hid in it, there are few of these, nice I would like to know what they are called. any ideA.

Looks like feather dusters

 

[lcj2046]

To me it looks like an Aiptasia. I had them before. no nudi branch they don't like the light. they are nocturnal

 

[ivandrago]

It's defiantly not aiptasia because those tenticles are coming out of a tube that's somewhat see through they look like some kind of feather dusters or tube worm
