**4 Things You Absolutely Need To Know**

Your goldfish bowl is an important element of keeping goldfish, a hobby that is growing increasingly popular these days. Technical knowledge of fishkeeping has increased to the extent it is now possible for anyone to recreate any aquatic landscape at home – complete with its life forms inside a goldfish bowl.

Whether it be a corral reef in your sitting room or an ornamental pond in your backyard, any fishkeeper can enjoy the pleasures of an enjoyable hobby at a modest cost and trouble. Goldfish care – especially fancy goldfish care – is becoming one of the favorites. If you were to imagine the ‘typical’ fish, then the shape of the common goldfish bowl would be the one that comes to mind.

**Setting Up A Goldfish Bowl? Remember This!**

When purchasing a cool goldfish bowl, the first consideration should be the number of goldfish you plan to house in it. In order to ensure the oxygen in the water is adequate to support all the goldfish, the surface area must be as large as possible, as compared to the amount of water in the tank.

For example, 2 containers might hold the same amount of water, but the surface of the water exposed to air can vary greatly between the two goldfish tanks. Just blindly getting a large goldfish bowl won’t help. Look at a goldfish bowl picture to get an idea of this ratio before deciding. Goldfish bowl size should be proportional to your brood.

**Buying Glass Goldfish Bowls**

Goldfish are special because they need a lot of space. In addition to being messy, they tend to grow quickly and also need steady water flow conditions. Pick a bigger glass goldfish bowl if you can afford it, or else plan to upgrade when your goldfish grow in size.

To work out the capacity of a rectangular goldfish tank in gallons, multiply the length of the tank by the height, and then by the breadth. This gives you the volume of the goldfish tank in cubic inches. You can convert this to cubic feet by dividing the answer by 1728 and then multiplying the result with 6.25

Take for example a goldfish tank that is 36 inches x 12 inches x 12 inches in dimension. The volume will be 3 cubic feet. When applying the calculation above, the capacity of this goldfish tank is 18.75 gallons.

The figure that is of more importance when you breed goldfish is the area of the water surface in your goldfish aquarium. This can be calculated by multiplying the length of the goldfish tank by the breadth.

We should allow for 1 inch of goldfish (not including the tail) for every 24 square inches of area. In the example we just used earlier, the surface area of the goldfish tank would be 432 square inches. Divide this number by 24, and you get 18. This is the maximum number of goldfish types you can put in this goldfish tank. It does not matter how the inches are distributed, as long as they add up to 18. As the fish grow, they must be thinned out to maintain the original 18 inches.

**Testing a goldfish bowl**

Once you buy a goldfish bowl, before using it is advisable that you check it for leaks. Keep the goldfish tank on a flat, solid surface. Fill it up with water. Leave it there for many hours. Then, look at the table-top for evidence of leaks, such as puddles of water on the table.

If a leak occurs, it may be repaired using sealants. Most modern glass goldfish tanks have already been sealed by one of these compounds, and the chance of a leak is really very small.

Still, it is best to check before you put your fancy goldfish into the tank.

**Goldfish Bowl Filter**

To prevent goldfish diseases, the water must be kept clean and frequently circulated. Goldfish bowls for sale often come with filters as an add-on extra, which you can negotiate to have included in the price. Good goldfish care means understanding all these issues and maintaining your goldfish bowl in great condition all the time.
