Had this in my chaeto for the last few weeks. Tried a week ago to get it out thinking it was a feather duster, but it vanished the moment the filter the chaeto currently sits in was turned off. Tried again the other day and found out why I didn't find it the first time. When it retreats it turns into a little ball of goo that basically looked like debris.
This was the view I kept seeing of it until I finally managed the other day to fish it out.
I placed it on a rock in the tank. It seems to have latched on, although it did move slightly up the rock from where I placed it.
I started researching thinking it may be a feather duster, but now not sure if it could be a Aiptasia or similar pest instead. It no longer tries to retreat when the water near it is disturbed, but I haven't tried touching it yet which seems to be suggested (will try that when I get home). Figured maybe the more experienced saltwater keepers on the forum may be better at IDing whether it is pest or not.
