This is their current nest/outworld setup. It's quite messy, with everything being combined into one structure, but it also does allow me to get a decent visual of them feeding
You can see from this picture its just 3 test tubes in a tall boxbox container from thecontainerstore. At first, I meant for the tube on the left to be a dry tube, but they started piling their trash inside. The tube in the middle is now the dry tube, after it ran out of water. Most of the workers and the brood nest inside of it. The last test tube is a water tube, which I take out to refill once it starts to run out. (Now, if I reach my hand inside to take the tube, they'll probably freak out and climb all over me)
Closeup of brood and majors
These new majors are soooo beautiful. They have heads which are larger than the queen, and their gasters are always bloated and huge. Once the majors darken, their legs and antennae and some parts of the head actually become black, which contrasts really nicely with their color.
I keep a cardboard box over their nest to keep the light out. I've noticed that less exposure to light seems to be better for their brood, although I might be wrong. This is what happens when the light comes on though...
My barrier for them isn't fluon, but it works pretty well. On the rare occasions one does manage to climb out, it's actually pretty easy to coax them back in.
Some more major pics cuz I can't resist
These two are actually my first majors in the colony. Their heads are much smaller than the newer majors, and a little smaller than the queen's head. You can see that the lighter colored one looks more like a median than a major, as it retains the golden quality of the minor workers without having much black color either.
