Well my tunnels have grown but I think that could be because of my cover and that I keep rotating it.
I do seem to have a lot of dead ants though. There are at least 3 or 4 in the tunnels that they do not seem to remove and there are 3 on the top although I'm not sure if one of those is just sleeping. I thought they were supposed to carry the dead out! I think they don't see it as their home though. Not even sure they all eat the gel which may be why they keep dying.
There is little to no downward digging either. Maybe I should ifnd some larvae.
