I have found these buggers adhered to all the pumps and on rock work especially in pump after a deep cleaning. They were all pristine white with red feather duster like heads best I can see. TINY! The red heads might have been the size of a pencil tip ( all lead on a pencil at sharpened end).
Hope this photo helps

They are good filter feeders, I used to have hundreds in one of my tanks years ago.
