It could very well be your water parameters, but you need to tell us.
Temp:
pH:
GH:
KH:
before we can figure anything out.
But generally speaking, neons are sensitive, Petco has dead fish piled up on their filter intakes and their fish have likely been exposed to some pathogen thanks to their rack systems-so the odds are very much against you buying fish there.
