Mine definitely doesn't enjoy high flow but where I have it gets random bursts which doesn't seem to bother it much. I moved mine off the sand bed yesterday as well....@tbrown3589 I put the Duncan where you told me to, but it was getting a little much flow. Moved to the tip of the rock on the other side, and it looks happy. It extended fully, more than it did on the sand bed, and it seems to be liking the low flow and medium light. Glued it on just now, and it looks good!
