I remember buying what was called "deco rock" back in the day. It was the live rock on steroids, it had a rainbow of colors of algae, sponges and feather dusters all over it. It was what sucked me in. Seeing all these different creatures, limpets, chitons, pods, etc come off and make the tank home. I think it was something like $7.00 a pound, this was about 20 years ago. Jesus I'm old. Luckily I was starting a 10 gallon, so I didn't need a ton, but it was cool seeing all the life / hitch hikers. I didn't get jaded on live rock until I put a piece in that had a Eunicid worm a gorilla crabs hidden in it. The Eunicid was about 18" before I finally was able to get him out. Sorry to go off on a tangent, but live rock definitely has it's pros and cons.
