It is a montipora and freshwater dips and sps corals don't mix. That said it seems to have a bit of polyp extension so it isn't dead yet. I would place it very low in the tank with medium to high indirect flow and then don't touch it until it looks good. Then you can slowly increase the light it is receiving. Eventually you will want to give it pretty strong lighting but not while it is stressed.
