You sound like you have it all figured out. For pixies, you can feed them anything you want TBH. They aren't picky and food is food. Feeder goldfish is good every so often and anything with bones so they can have that extra minerals. I use just a standard heat lamp with my pixies. As long as you don't use a heat pad you should be fine. I've said in other post, I usually go out in my yard and catch my pixies food.....like dragon flies, June bugs, and geckos/anole lizards. Good luck
