A possible concise summary is:
The narrator of the video is trying to save a colony of yellow crazy ants (the Golden Empire) from a parasitic mite outbreak. He introduces a cane toad (the Angel of Death) to the ants' terrarium (the Hacienda Del Dorado) to eat the remaining infected ants, but the toad does not emerge or feed for five nights. Meanwhile, he also quarantines some healthy ants and exposes them to predatory mites (Hypoaspis mites) that can kill the parasitic mites. He also observes a house gecko and some rhino beetles living in the terrarium. He then decides to replace the cane toad with some painted toads (the Death Sprites) that are more willing to eat the ants. He also adds a pond and plays some sounds of running water to make the terrarium more suitable for the amphibians. He ends the video with some questions and announcements for his viewers.
