Hi everyone, I'm back with another M. minimum question. After getting a bunch of help from people here, I've sucessfully moved the colony into the formicarium, no escapes (yet), and they've picked out a little corner of the nest to keep the brood in.
The one thing I've been unsure about is what foods they prefer. So far, I've offered them Sunburst, sugar water, pinhead crickets, and fish food (as a test). Since they're so small, I can't really tell if they're drinking from the liquid feeders. Or maybe they're just not hungry right now. For keepers of M. minimum or similar, what foods/liquids did you feed your ants?
