[COLOR=black][FONT=Arial]I had a friend that gave me a green star polyp frag. He adapted very well in my tank and was fully open for a month. The last 2 weeks he has been closed. I have been checking everything params, debris, and I moved his placement away from my other corals. I have a wavy hand and a small pineapple tree coral. They are healthy and growing perfect. The GSP was placed about 5in away from the tree coral before and I moved him to the other side of the tank 2 days ago. Do you think those two had an issue? I'm stumped. My lighting is perfect and installed new bulbs 2 months ago. The GSP did have some algae on him and in the picture it looks like he still does but I did get most of it off. In my old tank I never had this issue my GSP grew like a weed.[/FONT][/COLOR] [COLOR=black][FONT=Arial]All my other livestock are happy and healthy.
