So I have this poccilipora drag for about 18 months it has been doing forest and growing albeit very slow. I woke up yesterday morning and discovered a huge spot of tissue gone. Based on spot I suspected some predator but don’t see anybody bothering it. Now the next day I see even more time lose spreading and the surrounding tissue looks to almost be browning. I have a green slimmer fairly close that is doing just fine and other corals are fine as well. All parameters have been stable and nothing added in months. I was suspecting my pinchipn urchin grazed by it and tore skin off but the further tissue loss has me second guessing that. Any ideas? Should I just remove? Will-‘y rapid tissue loss affect other corals?
