Personally i dont think that thats what it is (still could be) try to get it out, and put it somewhere so that it could grow.
It looks like it has three polyps so it could be zoos or something and you dont want to kill those. Look at some pics of majano anenome and different kinds of zoos or other polyps and go from there.
Good luck
It is not a majano anenome, it is touching the xenia and its not stinging them. It looks like a small xenia or a green star polyp, or zoos, but its jellowy.
Can anyone id this star fish? Hear are a few pics, i got about 4 of them in my 8 gallon bio cube. I didn't buy them, i gess they are hitch hikers. Hear are a few pics.
I am pretty sure that the stars are asterina stars...they will reproduce throughout your tank (some people don't like them, I have never had problems with them).
It kind of looks like the thing that you are trying to identify may be some sort of zoanthid (closed up).
