The males don't live that long. I lost my original boys fairly quickly. Everything about what you posted in the intro sounds good, so I'm surprised they aren't taking off. I've heard of people keeping the regular and giants in the same enclosure so I assumed the care was pretty much the same.I have mine set up in a twenty gallon long tank. There are several inches of coco fiber with some oak leaves for substrate, along with springtails and Alphitobius diaperinus for a cleanup crew. I tend to run a wetter side and drier side with the substrate. I have a fake plant (adults favorite hang out) cork bark, and a few other cage decorations. For food mine get fruit/veggies (banana, zucchini, apples, carrots, dark leafy greens), dog food, and plain oatmeal. My temp range tends to be 77-82 degrees.
You know it is honestly hard to tell now because there is so many everywhere. Not suprising I notice a lot of white freshly shed nymphs in the more moister side. I think the adults prefer the slightly drier areas and I also think the nymphs favor it some to sleep. It is easier for them to dig. I almost never see the adults touching the dog food. The nymphs swarm that in droves however for the protien. To little of it and they will start acting as partial cleanup crew with the dead. I keep a steady supply of fruit/veggies in the tank, and that is what I see the adults eating the majority of the time. They seem to favor the sweeter stuff like bananas and apples. The nymphs on the other hand love the zucchini.
