Knotsack,
I am sure its a feather duster if it looks like a feather duster. I got several of them on my live rock. They have doubled/tripled in size since I got them about a month ago. Though I would recommend not poking at them with the net anymore, as it may stress them to the point where they'll pop their crown. It would grow back, but no sense in needlessly stressing them

thanx,one thing though, do they hide in their tubes or whatever? whenever startled

Yes they do hide or withdraw into their tubes. Be very careful. I recently moved mine to a bigger aquarium and he popped his crown. It has been a week and no sign of a new crown yet. Will continue to watch him.

Mine popped his crown almost 3 weeks ago and I still see nothing new growing back. I'm wondering if it's dead??
