Aquariums by Size
A good guideline for choosing an aquarium is how many fish you want to keep. A good guideline is one inch of adult fish (not including the tail) for every 24 square inches of surface area. This does not account for the difference between slim and broad fish, but this rule of thumb provides a starting point and greater margin of safety than other methods.
This guideline, by the way, is for tropical aquarium fish. Cold-water fish, such as goldfish, need 30 square inches of surface area per inch, which takes into account their much greater body mass per inch and greater oxygen requirements.
What all of this means is that when choosing an aquarium, it is best to try to select the one that has the greatest surface area for a given volume. If you choose a tank shape that offers less surface area, take that into consideration when stocking it.
