Zebra Danios are hearty and can typically withstand the cycling process, though it's not great for them etc. But you are likely almost there, as you are seeing nitrates. They prefer to be in groups of at least 5 or 6, so if you like the fish, adding them now probably won't be a terrible thing. Some may disagree, as nitrites are probably the most toxic, but I cycled my tank with Danios, (never lost one) though I'd never do it again, and after doing fishless cycling, that is the way to go (a bit late for you however)

Question, because I only have one little fish in a 36 gallon tank, is now the time to add one or two more Zebra Danios?
I'm working on getting 2 of those refillable 5 gallon drinking water bottles and filling with either RO or distilled water for changes to knock down the hardness. That won't happen untill the weekend but that's only 24-36 hours out.
