Aquarium Advice Addict
Criptix - liveaquaria is a good resource for just about everything saltwater. That rule of thumb for number of fish goes by inches (adult size) per gallon, not fish per gallon. Keep in mind that if you have a 50g tank with live rock, you don't really have 50 gallons of water in there, so calculate accordingly.
