In the wild, these tiny woodlice live under bark, in compost-rich ground, and around rotting plant material where temperatures stay stable and the microclimate is protected from drying winds.

Maintain a warm enclosure at 20-28°C, with 24°C ideal, and keep one side damp while allowing the other side to stay slightly drier. This moisture gradient is central to \u003cstrong\u003edwarf white isopods temperature\u003c\/strong\u003e success and helps prevent collapse from either desiccation or mould. A stable setup is more important than chasing exact numbers, but the best results come from matching the \u003cstrong\u003etrichorhina tomentosa humidity requirements\u003c\/strong\u003e with regular misting and good airflow.\u003c\/p\u003e\n\u003ch3\u003eFiltration and Ventilation\u003c\/h3\u003e\n\u003cp\u003eThese are not fish, so traditional filtration is not needed.

Keep temperatures near 24°C and avoid letting the enclosure dry out. The best breeding trigger is stability: steady humidity, plenty of food, and minimal disturbance. Many keepers notice that colonies expand faster when springtails are present, because the micro-cleanup crew keeps the environment fresher and reduces fungal stress.
