>>> and will not tolerat higher ph levles than 7.0
Most Neons sold today have come from farms. They are raised in regular water and are held in whatever tapwater the lfs has at it's disposal. Most aquarists then keep them in tapwater. I have often had Neons in tapwater well over pH 8.
The simple fact of farming them kills off the weaker fish and selects the fish that are more tolerant of higher pH, hardness and pollution levels.
Most wild caught blackwater fish will die from pollution first, pH is something that if changed gradually, many will tolerate.
It is quite possible to keep Neons in high pH water, they will not tolerate pollution. Newly cycled tanks are not suitable for Neons, (and other blackwater fish).
To the OP, there is nothing in your post which sounds like anything to worry about.
