Sometimes, soft corals go through phases in which they close up and start sloughing off layers of tissue. At first glance, the coral looks terrible and many assume that it is dying. Fortunately, that’s not the case. Soft corals do this fairly regularly, often closing up for a few days at most before shedding some tissues and opening right back up again. It will be almost as if they never missed a beat. So, next time your coral closes up for a few days, don’t panic. Just be sure to monitor it to make sure it does open back up.
