Stuck on Hermit Crab

[TBGator]

Well this hermit crab has been in the tank for a few weeks, but today I noticed something on the bottom of its shell. Looks like a clear Zoa, probably a filter feeder of some sort. I just want to make sure it isn't something bad. It is right below the opening on the shell.

Thanks!

Looks like a little feather duster to me..

I just though I would pass this on. I stumbled upon it trying to find out something else. Looks like the picture of the barnacle from this website
