New Coral identification

Hi. I just added two new corals and a feather duster worm to a fairly newly established 40g breeder reef aquarium. The fd and small button polyp are doing great right away. The second coral of which I'm unsure of its species seems to be doing 50 percent. I picked them up from a lfs a few days ago and they could not identify any of the coral frags. They just came in "assorted coral frag" label. It's a small white coral that branches out of a white "honey comb" like skeleton. About 1/3rd of it seems to be possibly dead. But the rest of it looked so good we bought it figuring we could nurse it back to life. It is slowly coming out of its shell over the course of two days. I will attach a picture. Any info would be great. Thanks!

Update- I just realized that I don't think it is possible to post a picture via mobile?
