Long story short, I ordered some mushroom corals, colony polyps, and rock anemones online. With the order, I was also sent an anemone that I didn't order. I emailed the company and was told they don't sell it and don't know what it is. I kid you not, they claim they didn't send it. I've tried finding it online, but I have never had an anemone. I need to know what it is because It's huge and mobile. It moves at a snail's pace, but it moves! This is my first post, and I hope this is the right place for this. The photos don't do it justice. It is stunning. The base is a pale pink with brighter pink marbling. Around the top of the base below the tentacles/arms are bright pink spots. The tentacles are a marbled grey and white. It came attached to the side of the bag. It attached itself to a square "rock", the kind of rock aquacultured corals are attached to. It is about the size of a young lady's wrist. The top is about five inches in diameter. I'm hoping it isn't an illegal or endangered species. I need to know what it is so I can take care of it, and to make sure it won't hurt the fish. I have one tailspot blenny, and a pair of naked cinnamon maroon clownfish in the tank. Some snails, macros, colony polyps, ricordias, a sponge, and one rock flower anemone. Thank you for any help.
