Cool thread Rob! Junk is definitely growing and looking well fed. What the hell is that skull thing inside of his enclosure? Haha. Just a couple of tips for the roaches, don't want to offend your setup at all. Feed them fresh fruits or vegetables once a week and then take the un eaten rest of the fruit or vegetables out after a day or two to prevent mold or bacteria growth that can end up killing off your roach colony. Also for roach chow besides the fresh fruits and vegetables offered I have a couple ingredients you can grind up in a coffee grinder: Dog food, cat food, kelp tablets, chicken feed, baby rice cereal, whole grain oats, fish flakes, milk powder, soy protein, dried alfalfa, ferret food. All high protein foods for your roaches and they'll love it, which will benefit your frog tremendously. That along with water gel crystals will have your colonies exploding with obviously monthly cleanings. Your temps are perfect for breeding them by the way.
That last shot is cool with the freshly molted nymph dubia. I'm not quite sure what a space heater is, but is it under the tank? If it is you might want to consider re-arranging a different heat source so he can spend time in the water as well instead of 95% of the time being burrowed under dirt for heat. Sorry if I come off as rude or anything, I'm trying to be more careful after that spencer guy lol. I think you're a cool guy, so no hard feelings. I'm open to criticism too! I'll post some pics of my pixie in a few days in a warm water bath when I need to clean his tank and you can give me some thoughts on my little guy too

. Take it easy.
