Fan looking thing?

Any idea what this thing behind my star polyp is? Has a long cord and a fan looking thing coming off of if.

They're harmless filter feeders and really neat to watch

What are they???

They're mini feather dusters. They stay quite small. They're harmless. I have some of the white ones also, some people get lucky and get tiny purple or pink ones.

I have tons of them. White, purple and red they are neat looking
