Bioactive custodians act as not only as a food source, but also invertebrate janitors included that will help to break down and recycle nutrients by consuming any waste organic matter within your bioactive system. They are designed for use in rainforest and temperate bioactive vivariums, or terrariums. They are not suitable for very setups as the custodians require a higher humidity environment. They can be used in planted set ups and will not destroy the plants.
