Hitchhiker Help! Srry No Pics,

Hi everyone, i love this site, and i just put my very first piece of live rock in today. Fiji. ok, so theres something in there, whenever i come near, it quickly hides in a little hole in the rock. I dont need to bump it or anything. It can see or something. Its doesnt quite look like aiptasia because the tentacles are more uniformed, and are a perfect circle. However, it almost does because they are shaped the same way, except for fans at the end!! So normally i would confidently say it was a featherduster, but it doesn't have a tube, and it doesnt just curl up, it dissapears!!

Its a featherduster, there are little ones that are absolutely everywhere on LR. They come and go and if you get one that stays for a while it will build its-self a little tube. I've never had one that grows longer than .5 cm., but I have had some that grow in the same color as the corraline algae that they are surrounded by. I've god some crimson red ones, pink ones, purple ones and even a few green ones. But mostly that drab tan or grey color.

Agree with the above.
I have a couple small ones that. for about the first week, would go into their hole in the lr just if someone looked at them. Now they're always out unless something physically touches them.
