TAKE A LOOK!!! Aquascape!

Just play puzzle with them.
Try and get the rocks to naturally fit together by just placing them against each other.
The natural dropped in look is really good at starting the process.

Just don't actually drop them. Did that with a frontosa tank once and blew the bottom out.

Side note...if siphoning is too slow for you this is a really fast and easy way to drain a tank.

To create a more natural look (if that's what you want - most of us do), try to use rocks of similar shape and texture. I have found it very difficult to incorporate flat rocks and make it look natural. I also love to make islands. You could try having just one cave, then have an island off to the side. If not, you can always build your current structure again. Imo, the aquascape is really one of the most important aspects of making the reef. A good aquascape can really make a tank look great, and a poor aquascape can really be distracting from an otherwise nice reef. I don't think I will ever be satisfied with my aquascape, and it is not often that I see aquascapes I am quite impressed with. Call me picky!
