This is personal preference. It is really hard to build the rock structure without some of it touching the back of the tank. Mine has pieces leaning on the back of the tank, but I also made sure that there is a lot of room back there for flow. It's kind of nice because I still get to watch the fish back there and have more room up front.

I believe seeing some nice clean sand up front adds a nice touch and brightens up a reef.
