You do realize that you advocated a bigger tank while also advocating sticking three fish in an 8 gallon tank? Three fish in an 8 gallon leaves little room for error...
Nanos are too popular to be discredited so quickly. Patience, commitment, vigilance, and research: that's all it takes no matter how big the tank. We basically both made that point already.
Honestly, my nano is pretty low-maintenance. I obsess over it more than I maintain it.
