filter feeder in sps

i dont have a camera good enough to take that pick but i am hoping to get an idea. i have an acropora in my tank with good polyp extension but one of the holes is larger and there is a fan that comes out to feed every few seconds. it reminds me of my porcelain crab. it isnt hurting the coral but i was curious

Sounds like a barnacle to me. I don't think they harm anything, I have had one on a colony in the past.

it's a feather duster, no harm to the acro
