Care Information

• Size: Mixed sizes.
• Diet: Rotting hardwood, leaf litter (oak, beech, maple, chestnut, Asian species), and lichen form the staple diet. Supplement regularly with calcium (cuttlefish bone, limestone, or powdered calcium carbonate), protein-rich treats (fish flakes, shrimp pellets) and vegetables (squash, carrot, zucchini, or sweet potato).
• Temperature: 20–26 °C. Room temperature is usually fine
• Humidity: 70–80%. Maintain a moist/dry gradient: one side humid with moss or damp substrate, the other drier. Mist lightly or use a dropper every week to maintain stability without waterlogging.
• Ventilation: Provide good cross-ventilation to prevent stagnation, while keeping humidity stable.
• Substrate: Substrate minimum ~5cm deep mix, organic soil, flake soil, rotting wood, sphagnum moss, and leaf litter. Add cork bark and hardwood pieces for shelter.
• Enclosure: 3L Braplast tub or larger. For growing colonies 5L and 11L tubs may be more suitable.

Isopods are shipped securely in ventilated tubs with damp moss for safe travel.
