Sorry to here you all are having troubles keeping them. They are nice to watch. To me they look like flowers in the water. Ill remove them later as we start getting back into the SPS 's. For now they are nice to look at and I love the soft corals. I know they will get out of control if I don't keep up with them. I think they like a nice flow but not crazy so near the overflow is a good spot for them, lots a food there. Mossjer, I put mine 2/3' s the way up my tank and in just enough current so they just barely sway in the water.
