Ok, so I've started to consider doing a jarquarium for all the hitchhikers, and weed coral which I don't want to put in my tank but hate killing. It's a complete experiment but looking into it seems really cool and fun to see what's able to grow in amazingly harsh environment. Im planning on spending almost no money on this project but would be interested in buying one or a few small pieces of live rock that have hitchhikers on them to jump start the tank. As I'm still just in the planning process this is more a feeler thread to find out if there are any lfs that carry rock with an abundance of diverse life already on them. Thanks for any help or advice.
