Coral ID

This is some kind of LPS, but I have no idea what it is.

It has sweeper tentacles that come out at night, but otherwise it just sits there, like a lump of, umm, crap. Sorry for the picture quality, it is in a hard spot.

Thanks.

Those are SPS, aren't they? This is definitely an LPS.

Actually, I think it is a chalice coral, similar to this: (greenmako was right)
