Hello. I've just added a bubble tip anemone to my tank. Probably more like saterday. So it's been a few days. For the first couple of days it just hung out on the rock it came with. Then yesterday it took a stroll around the reef. At this point it still looked good. But suddenly tonite it has crawled under a rock and is just sitting there. small and frightened. Is this normal. I know it will move around untill its happy. Maybe it needs a another day..... Any info ???
