(FroYurOwn)-I am jealous of that feather duster picture you posted on the first page, the one with the purple on it, its awesome.
(ReefCheeks)-I have alot of large feather dusters in my tank and when they start to shrink and curl up they are not doing good, they will shed their crown of feathers and then regrow it, if they are still no feeling good, whatever the reason, they will die.
