Hi all, been reading this site for a while - 9 months in on a marine tank after about 20 with a freshwater. I have many questions but for now I’m worried about my expensive bubble coral. It was beautiful however when we were away on vacation last week (we had house sitters for the dog and fish) my goby/shrimp decided to move locations and buried the coral. I had to dig around to find it. Anyway I think it was buried for a number of days and now it’s just a skeleton but some green still in there. Any hope getting this back or do I need a new one? Pic attached I think. Also this pink one was knocked over, it used to have long tentacles but since looks like the pic. Any advice would be great thanks! And yes, having a bit of an algae outbreak but it’s getting better.
