Red anemone with white tips

[pkgrif]

I have a small (less that a dime size) anemone with a bright red body and white tips that appeared in my tank. I have mushroom and zoos. I just want to make sure it isn't bad and will hurt anyone. Does anyone know what it might be?
Thanks

Any chance you can take a photo? Do a search on the board for Caribbean mushrooms, and see if that is what you have.
