I'm realling bad being creative. Just finished setting up my tank with live rock. Any help would be appreciated. I would like to keep some lps and sps. I'm not happy with my aquascape.
I would consider centralizing the rocks in the center more, and definitely use rocks with a flat surface on the bed, rather than as a "bridge" as it is now. It will look more natural. Really, if you just moved the flat rock to the sand bed, that will make a huge difference.
I personally would remove the flat rock all together (the flat bottom looks too unnatural to me, unless it is sitting on the substrate)......centralize remaining rocks like @PeaBrain said. I would also take one of the rocks and break it up into thirds. Having some smaller rocks to work with will make a huge difference....especially in a smaller tank.
