Springtails – Collembola spp. Springtails are microscopic, soil-dwelling decomposers that have become an essential part of modern vivarium keeping. As a live feeder, they are invaluable for raising the smallest of animals — including dart frog froglets, micro geckos, and hatchling invertebrates — providing a constantly self-replenishing food source that is impossible to overfeed. In bioactive setups, they serve as a highly effective clean-up crew, breaking down waste, mould, and decaying matter to keep the substrate healthy and odour-free. Easy to culture and maintain, springtails thrive in humid environments and are a must-have for any serious vivarium keeper.
