Fragging Hawaiian Feather Dusters

[Michelle]

Has anyone fragged these? Can you scrape the bottom of the tube off a rock or will this damage the worm? The ones I have are the large Hawaiian worms, not the small dusters.  Bought one several years ago and now have many.Picture not the best but you can see a new worm that was just expelled from the adult. View attachment 4262

Never had one myself. Would interested to know as well for the future.

I can't tell anything from this picture but, the colonies should start to seperate themselves. Small hangs where the colony can easily be seperated... The best time to seperate (the small hangs) is when the "feathers" are not extended.
