Please help ID

Can someone help me ID this? Little orange looking thing poking out the bottom
Was using my flash light looking at the tank and seen this thing sticking out the side? I stuck my hand in there and it like retracted,
Ended up pulling the coral out, took a knife and like scraped the bottom to scrape away what ever this pest was, re-dipped and put back in the tank.

Is it aiptasia? Or a feather duster?
Have had this piece for at least 4 months, first time I’ve noticed this.

I think it might be a feather duster, but to be honest I'm basing this on your description as it's too hard to tell from the image.

The latter. Common red one.
