Aiptasia?It came with my favia coral frag from SBB corals......I've never seen anything like it. Looks like a flower with black leaves and a red inside. Also has a fleshy bottom to it with white thin tentacles that were flowing from the fleshy part. Is this some type of anemone?
Its black though, like a deep black with a reddish/yellow center. Couldn't really see it that well.
It also seems to be reacting to the skunk cleaner shrimp actively when it comes near it to touch it. Looks like it had its fleshy part dig into the sand and now its just flowing there.
This is the best I could do
