20 Gallon Fish Tank

In the 20 gallon fish tank you can have as many big fish as you like. Most people mix small fish with big fish in the 20 gallon fish tank; however, this is not advisable because the big fish tend to eat up the food of the little ones and also they bully them around. It is rather advisable to get more or less the same size of fish that can grow together. In case you have a new addition you should take care that you gradually introduce the fish to the tank. You can lower it in a smaller and transparent container so the fish becomes acquainted to other fish without being traumatized by them.

For all this, a 20 gallon fish tank is the right size, and because of the suitability it is also the best possible choice for the beginner.
