I have an outbreak of Tube Worms or Feather Dusters (not sure what to call them) in my display.  I have tried manual removal and can get a lot out, but they come back fairly quickly.  They originated in my sump and I was ok with them there, then they migrated upstairs to the display.  To do a more thorough manual removal I'd need to take apart my rock work and disturb corals.  So after manual removal does anybody have any suggestions?  Would a Copper Banded Butterfly or an Aiptasia Filefish go after them?
