I didn't realise your ph was so high. I know that fish can become accustomed to higher/lower ph over time, but I also can't help thinking that you wouldn't be giving either the Uaru or Choc cichlid, whichever you choose, the best start. Both prefer softer water.

Yes
I was watching this thread and thinking, with an 8.2 pH, choices for this aquarium need to be thought out and researched carefully.
We probably should have been asking about water parameters much earlier.
And so. OP.....what are other water parameters?
Things like Total and Calcium hardness, even conductivity. You can find these on your water providers web site under "Drinking Water Quality results, or maybe even on your water bill
Although most fish as entities aresn't bothered by pH. or hardness
Certain bacteria thrive in a certain pH's, and some like the bacteria that causes chronic HITH are pH dependent, preferring pH at, or above 7.5.
So fish that have evolved in a soft water low pH environment often have little resistance to high pH hard water bacteria.
If it were me, I'd be looking at either moderate size Central Americans, like Amatitlania or Thorichthys, ......
or moderate sized rift lake Africans, there are hundreds of those species.
You should probably "Not" ...be looking at soft water South Americans like Uaru, Geophagus, chocolates or the like.
Its not the fish itself that needs to be adaptable, its whether or not the fish has resistance/immunity to the water type bacteria you have.
Spending millions of years adapting to waters, and the bacteria that evolved in pH below 7, does not bode well for them at pH 8.2.
