I purchased a beautiful flower anemone. I brought it home, floated it, and put it into my invert/ coral qt tank. The first four days it appeared fine but started to decline after that. By the seventh day, the picture of it on the rock is what it looked like. I coaxed it off but then discovered it had a hole in it! I don't understand what went wrong. The only tank mate other than the coral is a peppermint shrimp. I have another flower anemone in my display tank, and I've never had an issue with it. Needless to say, it didn't make it. I'd like to get a replacement, but I'm hesitant to do that until I have a better understanding of what may have gone wrong. Any ideas?
