[Poof No Eyebrows]

This guy has been in my tank for a year or so and I can’t remember what it is. It has all sorts of tentacles that come out of the middle in the evening. Any help would be appreciated.

Thanks guys. I originally got it for my daughter who picked it out over a year ago.
Side question. If I place another rock next to it will it grow onto that? I’ve always been much more of a softy kinda guy and really don’t know much about how hard types spread / propagate.
