I want to start a saltwater aquarium but don't know what setup should I do. What is the best setup for a beginner, fish only? I also read that I should also get live rock for a fish only set up, not necessary but will be beneficial. Does having live rock require special lighting? Also I have a 100 gallon tank (someone gave it to me that have all the necessary equipment for saltwater, even a bunch of dead rocks). I am looking to stock a couple of clown fish and some tangs. Also, is there any other sites or books I can get to learn more? Any help is greatly appreciated.
