Tiny thing growing out of a belladonna cluster that caused it to get weirdly white and fuzzy. Tried hydrogen peroxide then saw this guy, I might just chuck the whole cluster in the trash.
Just to add, this thing is tiny (those are small zoa polyps that it is in between for reference), and if I get too close the thing pops back down very quickly. Because of this, is it more likely to be a feather duster?
