Only in my experience, they do best with high light and medium flow. These are by far my best growers, they can go from a single polyp to 20 or so in a couple of months!
I have several colonies going. They seem to do better under mid level light and moderate flow. 150 watt MH around 4" under water with low phosphate and nitrate.
I have yet to see any of them thrive under heaver loads with high nitrate or overly bothersome flow.
I've got several mini colonies that I know have lineage to the originals. The more light they get the brighter they get, there's a little more straition and darker notes to them with more moderate light. They grow fast regardless of if in moderate or heavy light.
