Yes. Most fish do drink plenty of water, some continuously. Some fish absorb water through their skin and/or gills through the process of osmosis, and may excrete water that way, too.Check out this site:http://www.madsci.org/posts/archives/dec96/847855291.Zo.r.html

Yes
Freshwater fish drink through their gills whereas ocean fish use their mouths to drink.
