A freshwater fish is simply a fish that lives in salt-free water, such as a lake or a pond.
There are a number of things in water that make a fish live such as oxygen, sources of food, and many minerals.Contrary to belief, fluorine (fluoride) in tap water does not extend the life of a fish, and this is why fish keepers use water conditioner (dechlorinator) during each water change.
Both kinds of fish can live in a delta area. The line between salt water fish and fresh water fish seems to be getting blurrier. Sharks and other typically salt water fish are found many miles up stream in rivers that empty into the ocean. It appears that salt water fish adapt better than fresh water fish as the fish found in fresh water are not found out at sea.
