Hey Andi Looking at your new zoanthids some of what I see I think are just sir bubbles but the polyp on the far right looks like it has snail or nudibranch eggs on it. See the white specs in a comma.circular pattern?
Check out the nudibranch pics on this site

A fresh water dip would kill any nudis but not the eggs.
