If you are at all interested in setting up an aquarium Living Art Aquarium is the place to go. Tim (the tall guy with the reddish beard) is a wealth of information. If you describe your tank to him he will honestly tell you if the plant, fish, or invertebrate you are thinking about adding will work with your current set up; he cares more about the tank and the survival of its inhabitants than selling you an expensive fish.
The fish they stock are largely in great condition and they can special order you a fish if they don't have it in stock. They have a fair selection of equipment and tanks, but you might have to order some pieces online or get them from a generic pet store.
For a specialty store the prices are very reasonable; especially if you think about the fact that you are not paying for just the fish, but the advice you are given as well.
