Like the live sand, the rocks you are going to put in your tank are also "live" and contain useful bacteria for your tank's cycling process and helps sustain a good living environment for your fish, anemones, and corals. For me, setting up the live rock is the most fun part of setting up an aquarium. This is the point where you get to decorate and design your tank exactly how you want it. The great thing is that you don't have to depend on nature to give you the exact rock you had in mind. Many fish stores have the means to make and design man-made rocks that they put through a cycling process to make them "live." You do have to keep in mind that different fish require different surroundings. For example, if you get an eel you will have to have many small areas for it to crawl through and hide in. So make sure you read up on what your fish are going to need before you place your rocks. If you wish to change the layout you can, you just don't want to shock your fish by changing their surroundings all the time.
