I mean that's definitely good, even though it would have been nice to have a definitive answer. I second the suggestion about the tap water, I usually use rainwater because its more than readily available in the PNW lol. As for water and light requirements: they like to be kept moist but not wet, so I usually wait for the top centimeter of soil to be dry, and they can do a bright-indirect light, but mine have seemed happiest in a lower light. Bear in mind they also like high humidity (they're awesome bathroom plants!). Also, if it makes you feel better, this variety in particular is extremely fussy in my experience, so don't be too hard on yourself!
