Ok I recently added a few new corals. One of which was a relly, really nice bright Fiji leather. The first few days it was fine. I did a water change 2 days after I put him in and since there was some cyno bacteria near where I placed him I syphoned that out with my water change. He was pretty ticked and closed up of course. The next day he had not fully opened. Then yesterday he was opened but did not extend all the small polyps. Today is the same thing. When the lights are out he is all shrunken and closed up but when the lights come on he opens up some but doesn't extend all of his polyps like before. My water is still great and I am very anal about keeping all parameters right where they should be. He has been in there like 5 days now I think. All other corals including the SPS frags I added at the same time are doing great. Could it be the lighting? In the LFS he was halfway up a 100ish gal tank with MHs and I put him at the bottom to photo acclimate him. Should I move him up more? Since it isn't opening I'm afraid to really mess him him much and make him close up even more. Also, his color under just the actinic lighting isn't quite as bright as it first was. Any ideas? I must be missing something.
