The KH is high, at 180-240ppm, or between 10 and 13 dKH. This has no effect on fish whatever, but being bicarbonate hardness it does work to keep the pH stable. This means the p|H is very unlikely to lower much by natural means in the aquarium, unless the KH is "diluted" with pure water.
You can read how all this relates here:
So, back to the fish. As the gourami seems to have no trouble, the suggested corys shouldn't either. The GH is not high and that would affect them more. And I wouldn't rule out the Whiptail. The pH range in the profile has to have a limit but it is not cut in stone, and only because you have soft water I would suggest this species also is likely to be OK.
Last suggestion, as test strips can be inaccurate due to this or that, I would confirm the GH and KH with the water supply people, just to be sure.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
