Most novice fish owners begin with a freshwater bowl or other types of beginner fish tanks. A desktop aquarium kit complete with a freshwater fish tank, filter, filter cartridge, lighted hood, water conditioner, and fish food is the perfect way to get started as an aquarist. While these kits contain the basic accessories most beginner fish tanks need, there is more fun to be had in choosing your own plants, rocks, colored substrates and decorative ornaments. There are saltwater aquariums that have been specifically designed for display on shelves, while some are equipped with reversible backgrounds to change with your mood or home décor. There are even octagon-shaped fish tanks that act as unique tables, hold up to 28-gallons of water, and never fail as an interesting conversation piece for entertaining guests. In this article, we present the best 20 gallon fish tanks and 20 gallon aquarium kits.

Currently, we have Fahrenheit to Celsius, Gallons to Liters, Inches to Centimeters (useful for determining fish species sizes), UK Gallons to US Gallons, and also a calculator to determine the total volume of your aquarium. Please note that the total tank volume figure computed is a rough estimate and only takes into account your fish tank dimensions. It does not take into account ornaments, decorations, the substrate, live rock, etc. These items can have an effect on the total volume of water in your aquarium. This calculation is simply based on an empty tank with the given dimensions.Do you want to know "How many fish can I put in an X gallon tank?" This method for estimating how many fish a tank can support is superior to the traditional a "how many fish per gallon" or "per litre" rule of thumb, such as "one inch of fish per gallon" or "one centimeter of fish per litre". To get results for hexagonal aquariums, see our You went to the Pet Store, purchased the perfect 10 gallon aquarium kit, which probably inclued the tank, filter system, heater, aquarium top, light, fish net, and your first water conditioner sample. You purchase some gravel, a few fake plants, and...Use this simple form to convert the dimensions of your aquarium (ininches or centimeters) to a close approximation of its volume (in bothU.S. gallons and liters) quickly and easily. All you need is tomeasure your fish tank's length (from side to side), height (from topto bottom of the tank), and depth (from front to back) and you canfigure out how much water your aquarium holds!This calculator uses "surface area" to determine fish stock levels rather than gallons or litres. This is better than a calculator that uses volume alone, such as the common how many fish per gallon rule. (Reference: .) The surface of your aquarium is where oxygen diffuses into the water. The more surface area, the more easily oxygen diffuses, and therefore the more fish your aquarium will support. For example, a tall, narrow 29 gallon aquarium cannot maintain as many fish as a standard rectangular 29 gallon tank because less water surface contacts air. NOTE: Calculations assume the use of an air stone or a that disturbs the surface. Adding more air stones will not increase the number of fish your tank will support.Q. What about how many fish per gallon rules such "one inch per gallon" or "one centimeter per two litres?"
For starters, the one inch per gallon rule (or 1cm per 2L) only works for tropical freshwater fish; cold and marine fish need more space. Also, tanks are often not filled to capacity; space at the top and displacement by decorations and gravel varies from tank to tank. Nor does it account for the shape of the tank (a consideration as non-standard shapes become popular) or the needs of specific fish species. However, for standard-shaped tropical freshwater aquariums, the one-inch-per-gallon rule gives a similar result as the surface area rule. Regardless of the rule, the adult fish size and body type still needs to be considered--not the juvenile sizes most commonly sold in fish stores.
