Filtration, and it looks way better than the fake corals. I just added LR to my fish tank about 3 weeks ago. I've got a lot of really nice colors coming out on it, and my fish love to hide in the caves and crevices it has.
live rock is very beneficial to your tank. like mentioned above, it's natural filtration which will help keep your water quality better and it looks a lot better than fake corals and 'pirate ships' or what-not.

so your saying dont buy it from here?
I think you should buy LR from a physical store, where you can actual see it. This way you can pick the pieces with shapes you like. When you order online, you get random shapes that may or may not look good in your tank.
