this is not my actual pic, but by far the closest i can find until i post my pics. This is almost exactly what they look like, and there are 4 of them, Definately a LPS, and each of them are ontop of live rock which almost appear to be part of the coral too. I will take all angles of pics, but got excited when i saw this pic online after some searching. LFS had them labeled as moon coral, but i was skeptical but really liked them and got them for a steal at 50 bucks
