I have had a group of green star polyps for about a year now. They grew in numbers and even propagated over to next live rock. Last month I noticed a decline in health. Checked all water levels and all good. I do once month 15% water changes. Tank is 160 gal. Other corals doing fine. The star Polyps are pulling away from the rock to which they are grown to, sort of flaking away and no longer coming out and flowing with the current sort of only about 1/8 in showing where as before they shown about 1/2 inch on the denticles. Beautiful flowing green. The only thing I can find different is a slim-like material that is connected from the rock on which they are growing to the rock to which is next to it. This appears to be a slim- debre coated tunnel of some sort. I can remove it and it is back the next day. Any takers on this question?
