There are numerous examples of fish adaptions to terrestrial environments, lungfish being the most quoted. Mudskipper species are able to drag themselves around mudflats, in this case gaseous exchange is provided by gills.

Not to mention the snakehead fish in the news in the Washinton DC metro area. This fish can survive for about three days on dry land and can use this to migrate from one body of water to another.

Yes. Millions of years ago there may have been a time when large bodies were slowly drying up and those fish which could survive for longer periods of time out of water, while looking for another body of water big enough to support them, would have passed this trait along to the next generation.
