I got a couple thousand mini meal worms last winter, and fed them to my adult terribilis and adult trivitattus. Some of my larger tincs ate them too, but the terribilis loved them. The only problem is that they die real easily in a humid tank. I didn't try to breed or establish them, I just fed them to my frogs to let me recover some fruit flies. They are also a pain since you have to feed them into a dish, or the larvae go straight into the dirt and eventually turn into beetle like insects. I will prob. get some more this winter, but they can be a little of a pain. Good luck with them.
