An aquarium gives a very lively look to a living room. These days there are various sizes available in the market, if at all you wish to set up a tank for your pet fish. Read more and learn which size will be the best for you.
The sight of beautiful fish swimming in a natural background is a very relaxing experience. Watching bright and slimy fish glide through decorated water is much more than a pastime for many of us. Keeping and maintaining a fish tank at home has become an obsession for some. There are many advantages, like less attention and care in case of aquarium fish as pets, which attract people towards setting one at their home. But, which are the most appropriate sizes? It is important to have proper knowledge, as fish also need their space.

What is the Perfect Fish Tank Size?

The size of a fish tank is calculated in gallons―with respect to the maximum volume of water it can hold. There is no particular size which can be called 'perfect'. Fish tanks are available in sizes starting with a small pot of 2 gallons to a mammoth 200 gallons. But, if you want to set up one for yourself, does it alone give a clue what exact shape or dimension we are talking about? Definitely not. We need to describe the sizes more elaborately. Here is a complete list of basic aquarium sizes:
