Do fish become thirsty?

Only saltwater fish drink. In freshwater, the inside of the fish is “saltier” than the surrounding environment. Water moves into the fish by osmosis, passively, through the gills and the skin and the stomach. Fish have to eliminate all this excess water by peeing dilute urine.
