I got a zoanthid about a week ago at a local aquarium store that specializes in saltwater aquariums. The owner of the store picked it out for me as one of my very first corals (along with a mushroom and green star polyp) to get the basics down before adding more difficult corals. During the first couple days my zoanthid polyps were all open and looked healthy. Then the polyps closed up and have been ever since. All of my other corals, fish and inverts ante doing great. I've tried moving the coral frag around about every day to see if it likes a new spot better. Is my coral sick? Does anyone know what kind of zoanthid it is? Am I moving it too quickly?
Here's what my zoanthid looked like, and what it looks like now:.
