Arctic char, which occurs as far north as the short, craggy streams carved
out of the unfrozen edge of southern Greenland.

Off the top of my head, I don't know for sure. Apache trout (Oncorhynchus
apache) and Mexican golden trout (O. chrysogaster) historically occurred up
to 2,700 meters. Rainbwow trout (O. mykiss spp.) have occurred at 3,000 m of
the Sierra Madre Occidental. Speckled dace (Rhinichthys osculus) occur in
the higher benches of the Grand Canyon, at around 3,000 m. I suspect various
trouts have been stocked into fishless lakes at even higher elevations. This
requires further investigation.

Worldwide, it's a species of nemacheiline loach (Yunnanilus) that lives in
Tibet, in hot springs at around 5,200 meters. (Lake Titicaca is only 3,812
