I bought some coral last week from a website and they were doing fine for a few days. I bought 3 frags of zoo's, 2 mushrooms and a montipora. Everything is still doing fine except for the montipora. It closed up one day slowly and closed up tighter. I know this can be a number of things, but I just want some ideas. My water is fine with feedings of zoo and phyto plankton and supplemented with calcium, iodine, and a few other basics every other day. This is in a 12 gal nano... I thought about chemical warfare, but they normally get over that pretty quickly. At night, with the moonlight, you can only see a little of the polyps...used to be flourishing

. And it looks like it started to die off, it's just a lil spot at the top of the branch but that can't be any good at all. If anybody can help it would be greatly appreciated!!! Thanks for your time.
