Caribbean Mushroom,Pseudocorynactis a coralimorph, I've never heard of them harming anything when they are only small - Most people find them just minding their own business behind a rock or in a sump.If you read online there are mixed reviews though,some people think they can cause problems. there is a larger species (orange ball anemone) that has been reported to eat fish but I think it's like 6" with bright orange balls, not pink or white
Not sure if that helps but I think the ID is correct. I'd try googling the name and see if the pics match.
