My tank is currently up and running, it is stocked with some rock I found locally. I purchased some fiji live rock but the natural rock seems so much nicer. There are several anenomes in the rocks and some sponges that inhale and exhale water. I have several hitchiking crabs and fish. Lots of long red and green algae. The rock was part of a collapsing sea wall that was filled with argonite rock. I took 5 big pieces. I am likely getting into trouble by naturally collecting as far as parasites go but it is a financial matter at this point. I can spend hours in front of the tank each night and see something new each time. I even have a brittle star in the mix. My kids are helping in the measurements. Here are the pics , they are very blurry sorry. Thanks. http://www.iongun.com/reef
