Whether you’re looking to set up a brand new aquarium or planning to upgrade from your current setup, it’s easy to be overwhelmed by the quantity of choices that you have to make. (This is especially true if you’re new to the hobby, or if you’re just taking on a new tank.) If this sounds like you, then you’re not alone: many folks find themselves in your shoes.

So, It is important to know the number of fish that you can keep in a tank, because the larger the number of fish, the less space and resources each individual fish will have. Too many fish in one tank will also result in increasing waste and decreasing oxygen levels which cause the eventual death of the fish. 

The number of fish that can live in a 20-gallon fish tank depends on many factors. However, it is recommended that for every one inch of fish, you have 1 gallon of water

For example:

– 1 inch of fish = 1 gallon of water

– 2 inches of fish = 2 gallons of water

– 3 inches of fish = 3 gallons of water

– and so on.
