that is a good question. saltwater tanks are completely different then freshwater. there is no 1" of fish per gallon general guideline that tends to work in freshwater. the oxygen content is lower in saltwater, there are territory issues, size issues, the ammount of space lost due to live rock ( which in a 75 would be 100-150 lbs easy ) and so forth. keep it mind it is also better to have an understocked tank then an overstocked one.

Good answer. Another thought...

In freshwater the fish load is generally determined by the ability of your buffer system to eliminate the acids created as the biological filter breaks down ammonia and nitrite. This is not as much of an issue in a marine system due to the effectiveness of the protein skimmer, and our methodical testing of alkalinity and calcium. Without question, the territorial behaviors of the fish determine the ultimate stocking level.

And no, you can't just choose "peaceful" fish. Fish behavior is different in a marine aquarium. It just doesn't work that way.
