Feather Worm under attack
I have a large hawaiian feather duster that has been in my tank for about a year now along with a small yellow tang. I noticed today that the tang has been eating the tube of the duster. The duster now has deep holes in the tube to where i can actually see the body of the worm itself. there is only a very clear thin layer protecting the feather duster in its tube where it has been attacked. i moved the duster to a new location so that the tang can't attack it anymore.
My question is will the feather duster be able to repair its tube or will it come out to look for a new home. should i do anything or let it do its own thing??
