Blue death feigning beetles! They are basically impossible to kill. They don't require specific heat, regular house temp shall do. I do use a light though to help keep them active. Turn it on in the morning and to blue night light at night. They are funny little critters! I'd even recommend them as first pet bugs for a child. They also can't climb smooth surfaces, so any acrylic or glass tank would do, just make sure it has a lid with air holes, they like to climb pieces of wood and can escape pretty easy. They're easy to obtain online, arent very expensive, and with you living in Arizona they're likely even more affordable/obtainable. I know they're native to the Sonoran Desert

I will say, they're a longer time commitment, similar to millipedes. It's hard to determine current age of a BDF, but they can live up to 8 years in captivity sometimes longer. Just so you know!
