Personally I wouldn't be tempted to add any fish for a good couple of weeks yet, the dark start is good for cycling the 'Nitrogen cycle' but it wasn't until you put those plants in 1.5 weeks ago that the Biorhythm would have kicked off, plus I can see that a lot, if not most of your plants have not fully transitioned yet (I can see new growth) so they will not be assimilating fully and also adding to the soup as the existing leaves die off.
Once your readings are good Clithon Snails are a good first critter they will help with Algae, Biofilm and dying plant matter without multiplying or leaving eggs everywhere like the Nerites. Snails or not, I'd still wait a couple of weeks from this point before adding Fish or Shrimp, and then introduce them slowly into a lovely thriving aquarium, I'll wager you will have a better success rate.
Tank looks great BTW and I look forward to seeing it in a month or so's time, and it's also obviously yours to do with want you with, I'm only giving you my slanted view on life.
Cheers!
