Copper band butterfly. Mine didn't bother the corals at all but definitely took care of the feather dusters. Tough to keep alive though unless you feed frozen food daily.

IF feather dusters were a problem then I might as well nuke my whole tank. I'm completely overrun with them. One of the LRs is white in appearance it's so full of them.

If anyone needs some food for a finicky CBB just let me know.

+1 on Cbb taken care of feather dusters. Never touched a piece of coral

My coral beauty cleaned out my tank of those and clove polyps. He died last week in my power outage and they are already getting plague like again.

I have a coral beauty and yellow tang. They don't touch them. They are growing on my corals so I want to get rid of them.

From April 2011:
Is there a fish that eats feather dusters?

Well if they are returning after only one week and are already a plague, I guess your coral beauty did not really cleaned them out at all...he probably just bothered them so they would retract temporary.

My emperor angel loves all feather dusters! I buy them as treats for him LOL
