I need ID for these???

All of you are so good at identifying stuff. I have another cluster of little guys that I am afraid of. If you can help me out here I would really appreciate it. They arrived on some rock over 2 months ago and just started showing up this month...its the little white oval star thingies clustering on the rock behind the zoo. They look like something I might not want, but I don't think they are aiptasia but I could be wrong!!!

 

It's real hard to tell with that picture, from what I can see...
might be cup coral or miniture feather dusters.
Do you have a closer pic?

 

I had the camera set to macro and against the glass so I think that is about it I will try to see what I can do!!

 

Yeah, I was thinking feather dusters at first glance, but to my knowledge, they are not colonial, I don't think they would grow all together like that.

Then I saw the one on the sand, that looks more like an anemone. Are they the same animals on the rock and sand?

Can you enhance or blow up that pic at all? If you can't get another one?

 

It looks like feather dusters to me. I am going to try and find a pic so you can ID. Feather dusters will colonize, if fact I have seen worm rocks that can sell for up to $75.

And some more

Anyway if they are feather dusters you have nothing to worry about.

 

Now ,see! I learn something new every single day of my life!!! ;D
Thanks for the enlightenment!

 

This is great!!! I knew that dusters could colonize however these do not look the same as the dusters I am getting. The one right next to the rock is typical of the dusters I have been getting a lot of. They all have tubes. These don't close like dusters, that quick snap. They just sort of slowly close down when disturbed. We will see, but from what you are saying they are probably not going to hurt anything!!

Thanks again for aleving my paranoia! I still am questioning why these little guys do not have any sort of tube, but then again they are still small. The other tubeworms in the tank have tubes upon my first seeing them.

I am going to try a pic at a higher resolution and see if I can blow it up. When I blow it up at the current resolution they get grainy enough that you cannot discern their structure.

This is about as blown up as I can make it with this little camera...still learning the cameras capabilities.

Thanks Everyone,

Feather dusters for sure.
