What Sized Fish Tank Should You Choose?

Fish, like so many other animals, need oxygen to live. The way they require oxygen is to remove dissolved oxygen from the water and release carbon dioxide into the water. This is one reason that the size of a fish tank matters. The larger the fist tank, especially surface area, the more oxygen is available to the fish to extract from the water. So what size tank should you choose?

The best rule of thumb when choosing your main fish tank is to go for the largest size that your aquarium room will accommodate. A smaller sized fish tank will severely limit the number of fish you can keep. Besides, no matter how many fish you have, a genuine fish lover will always want more. If you choose to buy a quarantine fish tank,  it will be smaller in size than your main tank.
