polyp extention during the day is not a normal thing. I only had extension at night with all my corals, but for some reason people seam to like it. my theory is that if there extending there looking for food as the polyps are there food catching tools, but who knows, I could be out to lunch also... but from reading I did years and years ago no extension during the day was normal as they are feeding off the light, at night when there is no light or at times when the light isn't enough they will extend to both catch food and increase the surface area exposed to light.
