Bioactive terrarium

A bioactive terrarium is a terrarium for housing one or more terrestrial animal species that includes live plants and populations of small invertebrates and microorganisms to consume and break down the waste products of the primary species.

In a functional bioactive terrarium, the waste products will be broken down by these detritivores, reducing or eliminating the need for cage cleaning. Bioactive vivariums are used by zoos and hobbyists to house reptiles and amphibians in an aesthetically pleasing and enriched environment.
