Candy cane coral
Hey guys need some help here. Few days back i was doing a water change and as i took out my mp 40 it slipped out of my hand and it dropped directly at the coral. I took him out quickly from the sand but ever since then he has been shriveled up. I fed him some phytofeast live and he blew up (plumped up) but an hour later he shriveled back up. Any idea on how I can get him to open back up like how he was before?
