Choosing the Right Sized Aquarium Tank

Aquarium TanksHow big should your aquarium tank be?  The following table provides a list of commonly available tank sizes, their dimensions, and filled water weight.  When choosing a tank, be mindful of your space, lighting, and how much weight your structure can support.

Typically you want the maximum size possible for an available space to ensure stability.  Measure out your stand, desk, or shelf first before purchase.  Look up the manufacture specifications and make sure it's able to support the filled weight of the tank.  Tanks typically come in glass or acrylic, glass being less expensive and more scratch resistant; acrylic being more expensive and less scratch resistant.  Acrylic weighs less, but the weight difference is marginal when compared to the water weight.  

Also, pay attention to the type of lighting, the greater the height of the tank, the higher wattage light you will need in order to reach the aquarium substrate.  For newbie aquarists, we recommend assorted 10 gallons and the 20 gallon long (or larger if you have space) with a maximum height of approximately 12 inches.  This lower depth makes it easier for standard low-to-medium lighting to reach the substrate, and for plants to grow without expensive equipment.
