Just because they live underwater doesn't mean shrimp don't get fired up.

Two Indian whisker shrimp residing in a tank in Michigan apparently had enough of each other and began butting heads.

Enter the peacemaker. An African dwarf frog suddenly appears between the two shrimp with its palms extended, much like a teacher breaking up a playground tussle.

According to the video's description, the frog's intervention worked. After a few days, the shrimp learned to avoid each other and give peace a chance.
