I could have used her a year or so ago... My SPS/Clam tank was in good shape...but the little zoanthids looked sooooo nice.. UNTIL THEY TOOK OVER MY TANK!!
I was even contemplating finding sundial snails for control. From now on, I practice and preach that zoanthids, green star polyps etc. should be kept on "islands" in the sand, where they would really have to work hard to blanket all the LR in your tank.
