guppies are ok at 6.5 neon can live at 7 - 7.5
they are adaptable creatures long long generations removed from their true habitat
even so..why not try to replicate their lost world so to speak?
you just can not imagine how resilient these small creatures are. Here at my work a guy is a proud owner of a 30 liter tank with 4 mature scalare fish. gi figure

. and they spawned yesterday.
it is also a difference between THRIVE and survive right?

imo get 15-20 neons and 6 pygmy cory.
