Sorry for the delay killer, I've had too much on my plate. Here are the pics. The first one is a bit blurry but you can see that coraline has virtually covered the rock and it looks nice in the tank. The second pic has two rocks (on the bottom) in it which I purchased from someone on Craig's list who was tearing down her tank, I don't think this was originally "live rock" because it is too dense and uniform in shape however it still looks nice in the tank. The rock on top of the other two is another piece of lava rock I purchased and it looks great. Be sure when you go to buy your rock you really pick and choose ones that will look good in the tank. I like the really large ones that have lots of different size holes in them, the larger the better as they make great caves you don't have to try to engineer or worry about falling apart later.

You should not use lava rock it will leach heavy metals into your tank.
