More Giant Burrowing Roach

Two of the larger ones were fighting the other day, they fought hours and hours, created a impressive volcano shape pit. They didn't even stop when I disturb them, I had to separate them by both hands and hold them there for awhile for them to realize I am there, and so they retreat. Then they continue the fighting underground a few hours later, the pit was even bigger, when I lift the tub up and check, half of the bottom of the tub got hallowed out. This time, they fought for about 3 hours, until everything collapsed.

I tried to take a video of their impressive fighting today, and to my surprise, they were peacefully eating next to each other. I am speechless...
