Critter on my leather coral.

I am new to reef aquarium and found this thing growing on two of my corals. Any help would be appreciated.

Picture is very dark... Can you shine a flashlight on the part in question and take another pic?

From what I can see, I see some kind of worm, maybe a feather duster?
