How do fish drink water?

Answer 1

Freshwater fish absorb most of the water they need through their skin (osmosis), not through their gills. The gills are for respiration.
Saltwater fish actually drink the water the live in, as the salt in the water is constantly pulling H2O from their bodies in a reverse respiration, this is why some fish such as catfish are sensitive to salt in the water, but this is also why some fresh water fish are helped by salt to generate a mucous slime coat on their skin which is necessary for disease prevention. Proper electrolytes, magnesium and other elements are important for slime coat generation.

Another note, because most freshwater fish cannot drink their surrounding water (Salmon and others are exceptions), when you place these freshwater fish in saltwater, they actually dehydrate.
