Most Cubaris benefit from a clear moisture gradient (one wet side, one dry side). Little Seas don't need a pronounced gradient — they actually do better with consistently lightly damp conditions throughout the enclosure. They'll suffer if allowed to get any level of dry.\u003c\/p\u003e\n\u003cp\u003eAim for 70–90% humidity, with a target of around 75% as ideal. The substrate should feel consistently damp but not waterlogged. Cork bark pieces strategically placed across the enclosure help retain humidity and reduce watering frequency.\u003c\/p\u003e\n\u003cp\u003eIf you're used to Mediterranean isopod care (with strict wet\/dry zones), Little Seas need the opposite approach — uniformly humid rather than gradient-based.

UK summer temperatures often fall within range; winter heating is usually necessary. A low-wattage heat mat on the side of the enclosure (never underneath, to avoid drying substrate) connected to a thermostat is the standard approach.\u003c\/p\u003e\n\u003cp\u003eAvoid temperature fluctuations — stable conditions matter more than hitting any specific point within the range.
