I have a chunk of Real Reef rock that I want to sell (it doesn't work with my scape but it was established so I wanted to keep it for cycling), I was planning on popping it up on the local forums and Craigslist. I know it has friendly hitchhikers on it and I don't believe I have any bad hitchhikers in the tank). Would it be best to bring the rock out of the tank and dry it out first, or leave it in my tank until there is a buyer? And what would be a fair price for a 5lb chunk of rock? Is it even worth selling? Thanks for your thoughts!
