I can't tell what the first one is but I have the second one in my tank, I did buy it and I love it. I believe it's called a brown star polyp. I have a little colony of them and think they look like a daisy flower....love them!!! I have mine touching mushrooms and other polyps and it's doing no harm. I would keep it.
