It’s been estimated that as many as 26 million Americans keep fish in home aquariums. If that figure is accurate, the hobby is the second most popular in the U.S. right behind photography. And, as a glance at the yellow pages will show you, the term aquarium hobby isvirtually interchangeable with tropical fish hobby.

Why the almost total emphasis on exotic fish? Well, it’s certainly not because of any shortage of native ones. Over 700 species of freshwater fish are found in the U.S., and as you’d imagine, more than a few of them are suitable for the home tank. In fact, as a group, they possess several advantages over tropicals:

  • Native fish are less expensive than imported or specially bred fish. If you content yourself with a selection of species that can be collected near your home, the cost of the fish themselves can approach zero. (Of course, as with any avocation, you can “get technical” and spend a fortune, as some native-fish hobbyists do, on far-flung collecting trips for rare and unusual fish.)
  • The costly and energy-consuming electric heaters necessary to insure the survival of most tropicals can be dispensed with. This fact has misled many folks to think of all our northern fish as cold-water creatures. True, there are coldwater fish (the trouts being the most familiar examples), but they’re a minority among the North American fauna. The difference between most of our native fish and true tropicals is that natives are able to tolerate cold water. Given their choice, though, many northern varieties would prefer to skip winter altogether and stay in water between 75°F and 85°F. (Because of this, natives can be kept with tropicals in heated tanks, if desired.)
