Hey,
I recently got some LR and it came with some corals on it.
I have recently noticed a weird little invertebrate on my LR and I was hoping someone would know what it was?
Another thing about it is that when it gets scared (say if I were to walk past) then the top part would go down in to the bottom part.
There is 2 of these in my tank that I can see except one on them has differently shaped "feathers" to the one I have taken a picture of. instead of "feathers" coming out from all around it, it just has "feathers" that look abit like a hand fan.
Thanks,
Joe

It looks like a featherduster to me, They a one of the beautiful harmless hitchhikers you can have on LR.

Here is a link on good and bad hitchhikers, They mention featherdusters and go into more detail on them.

The thing on the top in the middle is a feather duster. The polyps on the other parts of the rock look like clove polyps (clavularia sp.), but it's difficult to tell since the polyps are not extended in any of the pics.

Thought of Xenia at first glance as mentioned on other thread, but agree with H2002 that it maybe Clavularia or Anthelia. Should be able to tell better once polyps are well extended/opend.
If this and other came in as part of LR, cant ask for more!!!
I am thnking these rocks may have came from another reef tank as these corals dont look like most Wild sp. Regardless, what a good deal! Take good care of them.

Thank you all, much appreciated!
Oddly enough, the LR came out of the standard LR tank at my aquarium store! Somebody must have accidently put the LR into the standard tank and not the premium!
I think the LR came from The Great Barrier Reef.
I plan on getting 2 clownfish and some other small critters but I need to find a aquarium store that doesn't get the fish from The Great Barrier Reef because the clownfish populations there are going down, mainly because of anemones being bleached.
Thanks again!
