Exo Terra Medium Corner Cave PT3196 | Reptile Humidity Hide

The ET Medium Corner Cave is a ceramic humidity hide designed for reptiles, amphibians, and invertebrates that need a secure, moist microclimate within their enclosure. Measuring 9.5cm (H) x 18cm (W) x 13cm (D) with a 130ml water reservoir, it fits neatly into the corner of any terrarium, keeping floor space free while adding meaningful functional shelter.

Hygroscopic Ceramic Construction

The cave is made from a hygroscopic ceramic material that naturally absorbs moisture from the built-in water reservoir and releases it gradually into the surrounding air. This passive humidity regulation keeps the microclimate stable without any powered equipment, reducing the kind of rapid temperature and moisture fluctuations that cause stress in sensitive species.

Shedding, Hydration, and Respiratory Health

A consistently humid hide directly supports the shedding process by softening the skin and reducing the risk of retained shed. Maintaining adequate ambient humidity within the hide also contributes to respiratory health, as chronically dry conditions are a known factor in upper respiratory infections across many reptile and amphibian species.

Egg-Laying and Breeding Use

Filled with moistened moss — sphagnum or forest moss both work well — the interior becomes a suitable egg-laying site for a range of reptile, amphibian, and invertebrate species. The enclosed, humid environment gives gravid females a secure location to deposit eggs with conditions appropriate for early development.

Space-Saving Corner Design

• Corner-fitting footprint makes use of otherwise dead space in the vivarium
• Creates additional three-dimensional dwelling space without dominating the enclosure floor
• Natural aesthetic integrates into tropical, forest, and bioactive setups without appearing out of place
• Water reservoir should be kept filled to maintain the microclimate consistently

For keepers who want a low-maintenance, naturalistic hide that actively works in favour of their animal's health — supporting thermoregulation, hydration, and shedding in one compact unit — the ET Medium Corner Cave is a straightforward and effective addition to any suitable enclosure.
