Minimalistic aquascapes have become very popular today and I am certainly a fan of some of the Negative Space Aquascapes folks have created using dry rock. However, when you do things right with a SPS dominant tank the acros will eventually hide most, if not all, of that rock.
Here are some before and after shots of my tanks. The first is my old 225 gallon tank that was aquascaped with two large islands with a decent amount of space in between. Over time the SPS in the tank grew a lot and covered up all of the rock.
