Hello! The other day I got a bubble tip anemone, and after acclimation he very quickly found a spot to attach to. The next day, he opened up much wider than he did my local fish store. I have had him for about a week, but when I woke up today he seemed shriveled up and his foot detached. This is my first saltwater tank, so I am worried he may be dying. Any input/suggestions? (Below is the anemone wide open, and the anemone today)
