I have a very large indoor tank with very
passive and friendly fish. I want to add Koi to the family
can they adapt to water temps between 80 to 82 degrees.
Please reply Thank You

That tank had better be 250 gallons-plus and fitted with
a pond-grade bioconverter if you want to have any chance
at maintaining water quality. Koi of almost any size will
easily overwhelm even the fanciest of aquarium filters.
Koi grow very rapidly, and while not
aggressive, will tend to look at anything not clearly koi-like
as a potential food source. They "garden" constantly,
and will guarantee a murky atmosphere in any gravel-bottomed
tank. A two-inch koi, grown indoors and fed regularly, will
triple in size within two months while increasing its ammonia
output almost tenfold.
Koi will not do well at the temperatures
you describe, either. They are cold-to-cool-water fish,
and do best between 65 and 75 degrees. At 80 degrees, most
koi keepers stop feeding!
Koi are not indoor fish. Bad idea.
Sorry.
