Zoas are really coming into their own, started off with mostly single heads. I did lose a few, particular types didnt take to high flow a great as I wouldve hoped. Z.sansibaricus and sociatus took no issue, and so has gigantus surprisingly. The "krak" type zoas now being brought in have also responded very well to high flow. The one thing I have noticed is damage to the skirts on some polyps, which may just be my urchin. Montis still look like crap though.
