I am a beginner saltwater aquarist but I have a bachelors in fisheries science so I have some knowledge. My question is about live rock in an aquarium. I know that is nesscary and is and excellent natural filtration system but I worry about how it is obtained... is it being harvested from life reefs? How much damage does the harvesting do? I have heard that it is illegal in Europe, so how do they maintain thier tanks?
And as for fish and corals is ther any go way to guarantee they are being harvested by sustainable means?
