Im interested to hear what the experts think. Im not sure anyone is going to be able to id it in its current state...It def doesnt look happy. I would suggest researching it to be sure but Ive been told that when you have an acro that has bleached its best to cut off the bleached skeleton or cut off the healthier pieces and reglue as it will/can grown unwanted organisms on the bleached sections that will actually hinder the rest of the coral from thriving. Kind of like rot on a piece of wood...cut the rot out to stop the spread. Id be interested to see how it changes a month from now
