Oh, I totally get the excitement! Carnivorous plants are so fascinating! You're right about the distilled water; these plants like their water pure because they come from environments with nutrient-poor soil. Tap water can contain minerals that aren't great for them.
As for feeding them, you don't need to worry too much about providing bugs if you’re growing them indoors, especially if they're in a location where they can occasionally catch a bug or two. They can survive without additional feeding, but they might grow a bit more robustly with occasional live prey. Just remember, their natural diet in the wild is mostly insects like flies and spiders. And yep, definitely skip the fertilizer-these little guys get their nutrients from their prey, not the soil! Enjoy your new plant buddy!
