It’s been about 48 hours since introducing the ants into their habitat. The tunnels are growing, and the gel clumps are too. The second tunnel has looped back up to the top, and the first tunnel now goes to the left, reaching the top and bottom of the gel.
I’m sad to report that last night I observed what I thought was a dead ant. This morning, my suspicion was confirmed. Interestingly, the other ants seemed to have ripped apart the dead body, leaving the head and body and legs laying everywhere.
