Ant Farm Update
The ants hanging out in the bottom corner of the habitat. They have cleared the gel out of the whole area and they congregate there. Today seems to be some sort of Sabbath or something - they're all resting.
Back view of the habitat.
Ant in the hole. Top view showing an ant entering the tunnel. They have created a valley along the center of the surface between the entrances of the tunnels - a little highway between piled-up mounds of excavated gel.
Front view of the habitat. You can see how the tunnels weave and branch and intersect.
