Default CO2, PH levels and fish

Maybe I missed a basic concept here - can someone explain this to me?

Assume, for the sake of argument, that straight out of the tap, my water has
a KH of 2 and a PH of 8.

So, I add CO2 to 15ppm, which drops my PH to 6.6.

Now the question: Do I look for fish and plants that like a PH of 6.6, or
do I still
look for fish and plants that like a ph of 8?

Thanks in advance
