Overpopulating A Tropical Freshwater Fish Tank Is A Bad Idea

Two questions come to mind when you want think of keeping tropical freshwater fish; the size of the fish tank and the number of fish that you are going to keep. You have to remember that the bigger the space the happier the fish will be. Do not go for the number of gallons that the fish tank can hold since gravel and rocks added together with the aquatic plants usually reduce this space. You need to know that there is a danger in overpopulation like incidence of diseases and aggression. A big enough sized fish tank is always recommended.
