My orange plate coral is not looking like itself when I say this it's hard to pinpoint the problem. This morning it was swollen looking for some reason it was pushed up to the coral next to it so I moved it and now it doen't look swollen anymore. But I noticed it's mouth was open some today and now it's closed. Nitrates 0 salinity 1.022 no ammonia everything else is normal acting. I'm currently in the process of trying to raise my calcium using purple up. Is he dieing if so is this going to be a problem?
