At the beginning they wouldn't come out as much (during the first week). As time went on they have pretty much come out as soon as the timers turn the lights on each morning. I have noticed that at the beginning the polyps were much shorter when they came out, than they are when they come out now. They also seem to be affected by flow because at my LFS
they were in an area of pretty high flow and their polyps weren't very long at all, in my tank I have them in a moderate flow area and they seem much happier.
