They're all happy and fat, to say the least!
Btw, this is a shared colony tank — it's also where I breed isopods, springtails, earthworms, etc. There's a common lined snake in there too, keeping the earthworm population in check since they were WAY overpopulating before. They're still overpopulated, honestly, but at least it's more stable now.
Everyone's peaceful. The lined snake is fat and happy, can easily get away from the roaches, and has plenty of humid hides. It even eats a nymph here and there from what I've seen.
This is genuinely a balanced ecosystem enclosure. I started this project years ago — honestly lost count at this point — and it's been a real passion project. My original question was: given the right resources, could MHCs and Dubias adapt to a local Midwest forest floor environment? Obviously winter would wipe them out, so that's outside the scope of the experiment, but I wanted to see if, given the chance, they'd settle in and become just another part of the ecosystem. So far, they have — everyone's thriving.
I think it's an interesting experiment because it raises the question: given enough time to adapt to Midwest conditions, what insects could potentially invade this region? Maybe quiet invasions are already happening and we just haven't noticed yet.
For me it's a small-scale, short-term case study in adaptation — watching native Midwest species and two total outsiders (MHCs and Dubias, from completely different parts of the world) balance out and coexist in one tiny ecosystem.
In the tank: millipedes, snails, isopods, springtails, earthworms, soil centipedes, slugs, the roaches, and the lined snake. It all just works together beautifully. :)
I love sitting up all night watching them — the tank's at the foot of my bed, and observing how the whole thing self-adjusts feels like watching a nature documentary in my own room. I really love this 20-gallon setup.
Wanted to share this project and see what people think. I know some parts might be controversial, but my goal has always been to replicate a Midwest spring/summer environment — every soil creature included — then introduce the roaches and watch how things adapt. If I ever saw genuine harm happening to any animal, I'd dismantle it and separate everyone immediately. So far, though, everything just works. As nature intended.
