Agree. I would also ask about the hardness. Presumably the water is medium hard or harder with that high a pH, but this is not necessarily so, and the GH (general hardness) and KH (carbonate hardness or Alkalinity) is also important as they are somewhat connected to the pH.
As the well water is not municipal, you will have to test it yourself (rather than ask the water supply folks). Will the fish store test hardness? That would save you buying the two kits and only using them once. If they will, get the GH and KH and ask them to give you the numbers, not something vague like "hard" which tells us little if anything. Degrees of GH is significant as it affects fish, as does pH.
If you want to read more background on hardness and pH, here's my article: http://www.tropicalfishkeeping.com/f...quarium-73276/
So to the fish; there is some adaptability but this is limited and it can have detrimental effects long-term. You can read more in my article on stress: http://www.tropicalfishkeeping.com/f...um-fish-98852/
Before deciding if it is feasible to adjust the water, or necessary, we should get those numbers so we will know what will be required. But in the interim, you can browse our profiles [second tab from the left in the blue bar across the top of the page] for fish that prefer hard water and some that will manage depending how hard it turns out to be. There are rainbowfish (though only 3 species so far) under Atherinids, some small fish under Cyprinids, a few under Characins, some cichlids, and some under Catfish. Then of course all the livebearers. And finally, in a large tank, rift lake cichlids.
