The choice of freshwater aquarium you plan to set up often begins with the choice of tropical fish species you would like to keep in it. Besides personal preferences, there are many other important issues to be taken into consideration: each fish's adult size, behavior, water preferences, feeding habits, compatibility with other species, and more. In this section you can appreciate beautiful fish photos taken either by me or by friends from the net, representative of the many thousands of species available in the hobby. But you should also pay attention to the information in the tables, since it will help you decide whether that fish is appropriate or not for your existing or new aquarium.
