My best guess is a very small Branching Montipora (Montipora digitata) do you agree?

Stylophora?

Looks similar, but seems to have little nubs on the polyps while these are more like an open hand or something... If that makes any sense.

A troubled Stylophora.

Wow, yep stylophora looks spot on! It was a bargain bin buy, the polyps weren't out at first, and you can see the center is mostly dead, but there is tissue coming back in certain areas! Thanks a lot, is there anything I could do to help it other than keep about 10ppm Nitrates and decent flow?
