It's not legal for divers to take the rock and sell it off or give it away. You need a permit I believe to harvest off the coast if florida so it has to be similar elsewhere. I wouldnt take the chance. You can save a couple bucks but better off just getting alot of base rock and seeding it with some live rock.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
