Hi everyone, i really need some help, in the last week my green elegance coral has started to look really wierd, shrivelling up and closing up and i think it might be dying. it has been in our tank two months and i have never seen it look like this before. Since its arrival we have done nothing different we haven't added anything except the orange soft corals and our water changes and tests always seem to be normal. the hermit crabs started climbing on it today and i hear thats a bad sign, PLEASE HELP ME to save this beautiful coral, im so sad that it seems to be struggling! any info you have will help, thanks so much, Sam x
