Starting your first aquarium with a 20 gallon fish tank is a wonderful idea as it is small enough to be easily managed and will provide sufficient space to keep your favorite fishes. For starters, many people would like to keep gold fishes as they are very beautiful and are a source of attraction for many people. Though it might seem like all gold fishes are the same, there are different kinds of gold fishes available in the markets. However, they are all very beautiful and would make perfect inhabitants for your small fish tank.

Small fish tanks are particularly appropriate for small environments and add a soothing touch to the environment. A 20 gallon fish tank would certainly be appropriate for a small environment like an office or a small living room. There are a number of other fishes that can be accommodated in such small fish tanks but people mostly choose gold fishes because they require less attention and care and are thus perfect for people who do not find to take care of their pets.

Many children are particularly fond of gold fishes and a 20 gallon fish tank would be ideal for small homes. However, no matter how strong some fishes may be, they are still living creatures and require care and attention which must be given to them to ensure their survival. One should use proper filters and water pumps to ensure proper circulation of water. Circulation of water is very important as it helps keeping the water clean and thus increases the time span between through cleanups.

If you are a novice at keeping aquariums, there are many guide books available in the markets which provide a thorough guide on how to take care of your aquarium and ensure survival of the inhabitants of the fish tank. When choosing gravel for your small fish tank, it would be appropriate to get small sized gravel as it would ensure the proper flow of water through the gravel. Circulation of flow of water is very essential for providing a comfortable environment for fishes inside the tank.

Another important factor which needs to be considered is the use of medicines for purification of water. There are different medicines available for the purification of water which have not effect on the fishes but are powerful enough to kill harmful bacteria in the water. Therefore, these medicines should always be used whenever water is changed in the fish tank to ensure survival of fishes.

One of the many reasons why most fishes die very soon is that they are generally over fed which is not a good idea. Fishes have a tendency to eat anything they are given, however, the processed food which is used for most fishes is not the same as raw food and thus over dosage can result in dire consequences.

A 20 gallon fish tank is sufficient for keeping small fishes and other small sea creatures like turtles etc. Many aquarium shops provide pre-built aquariums which include everything from gravel to temperature sensors, air filters and pumps to give the buyer a good start. These are properly calibrated to match the size of the fish tank and make sure the environment of the fish tank is suitable for the fishes. So if you are a beginner, enjoy the pleasures of a pre-built 20 gallon fish tank.
