I have a very hard time believing this, nor have i heard this anywhere else. If this is true, then a coral with little poly extension should grow faster than a coral with good polyp extension, which i have also never seen before. I have always seen when you dont have good polyp extension, especially for extended lengths of time, the coral dies
IME~This is not a blanket idea;
LPS~ is just a large digestive organ, with little or no zoaxanthellae in the feeding tentacles, so if there are feeders out, it is hungry and attempting to feed.
feeder extension=hungry
SPS~ is different, it can only consume very small micro plankton and at a pretty slow rate, and also uses the entire polyp for feeding/ photosynthesis, so the more the polyp is extended the more it can do either.
feeder extension=healthy
softies~ in general do not have any alternate behavior for feeding/photosynthesis, so either its happy, or its not.
none of my acan lords will have feeders out at all during the day, but the last one I got a week ago has yet to put its tentacles away, it was obviously in a system that was fed way less.
