Freshwater fish do not drink water. Their body fluids are more concentrated than the water they are swimming in and water from outside is absorbed through their skins and into their bodies by osmosis, surplus water is then excreted in the normal way.
Saltwater fish on the other hand do drink water. Their body fluids are less concentrated than the surrounding sea water and water from within their bodies is sucked into the surrounding sea water by osmosis. They drink the sea water in order to replace the water they have lost.

Freshwater fish do not actively drink water, but absorb the water through their skin and gills. On the other hand, saltwater fish do actively drink sea water. Their gills process the water and take out the salt.
The salmon is an interesting example of a fish that lives in both fresh and salt water, and consequently, they have the characteristics of both types of fish. Salmon are born in fresh water, and migrate to the ocean. While living in the ocean, they drink saltwater by opening their mouth; their gills then rid their bodies of the salt and minerals. When the salmon enters freshwater streams to spawn (lay eggs), they stop drinking the water and instead absorb it through osmosis. (Osmosis means that the water passes through the cells of the fish's skin into its body.)

Some fish drink the water they swim in, while others absorb it through osmosis. It just depends on whether the fish lives in freshwater or saltwater.
