So I have a Pheidole bicarinata colony. I caught the queen from last year, she had a few workers which I fed peanut butter and insects. Uhhh can't say that I've kept them well fed at all. They're small enough that they're able to forage outside of the plastic container, and even with that I still find them gathering bits of nourishment from hollowed out insect carcases I should have removed weeks ago.
Despite my lack of care Uhh.... the queen seems to conjure up eggs with the use of magic. I'll just suddenly see a massive amount of brood in the setup. It's almost like every ant has their own larva to take care of.
This was a new setup, they just moved in today. Their old test tube setup was completely black with mold, leaking water, and they had started to dig into it forming a mass of gray cotton shavings to cork up the front of their test tube (right). As this mass of cotton marked the colony entrance, moving them to a new tube was as simple as removing the grey fuzz entrance and putting it into the new tube, then dump the colony from their previous setup. As the ants were small, and their tube was leaking water I couldn't get them all out so I had to use slivers of tissue to soak up the minor drops of water.
I'd placed the old tube back into the setup, something I never advocate because colonies will always just move back into their old setup. However the colony odor on the gray cotton fuzz they'd made was so strong at marking the entrance to their nest that they moved into the new clean tube (pictured above) even with access to their old one.
