I believe that if it's an anemone it's a pink ball anemone. They are pretty creatures but they DO multiply in your tank. When I researched the ones I'd found in my tank they were reported to have a pretty powerful sting. These only get about 1/2" max and they are pretty but they do multiply. I started with one or two less than a year ago and now there are at least a dozen. I have noticed that those I've inadvertently smashed (Really I did it on purpose.) have not come back and I don't believe that there was a significantly different increase in them after the squishing.
I suppose it's up to you to decide if you want to leave them alone and watch them or get rid of them. Hope this gives you some place to start your search for info.
