I also agree that they like lots of flow. Whenever I put a few zoas on the side of my tank, which is partially blocked by rocks, they do not do as well as on my sand bed with open flow.
I have plenty of flow as I have sea swirl on my return, a vortech and three nanostreams on a controller. This is just my experience as there are more knowledgeable people on this forum.
