The video shows a close-up of a terrarium with several poison dart frogs. The frogs are brightly colored, with some being yellow and others being blue and black. They are seen moving around on the leaves and rocks in the terrarium, which is filled with green moss and plants. The frogs appear to be exploring their environment, and their movements are quick and agile. The terrarium is well-lit, and the colors of the frogs stand out against the greenery.
