Looks like most of your candycane coral over on the side is dead, I see like 1 polyp and the rest is skeleton. your elegance doesn't look happy either, it's suposed to be out and swaying not sucked into the skeleton like that. Your anemone shouldn't be where it is getting no light, it will die in there. The fact that you're asking about amonia leads me to believe you have some? If thats the case start changing water because most living creatures don't handle amonia very well...
