Agreed. Active fish need more space than less active fish. 2 inches would be my max, but really the smaller the better since that means you can keep a larger school.
Also, a lot of people keep their wcmm in water warmer than 72, and you'll find that there are a number of "tropical" fish that do well at 75. As an example, none of my tanks are heated - the tanks drop to about 74 in the winter.
