The manufacturer informs:

Lucky Reptile Frog Cave was developed specifically for frogs, like many species of dendrobates that lay their eggs in small caves.

The Frog Cave corresponds to natural nesting sites, offering animals in the terrarium a safe, well-controlled nesting site.

The system comprises a shell that is filled with water , 

The shell can be easily removed and lifted so that it can be easily checked

The Frog Cave is made of robust resin with a very natural appearance and can be cleaned and sterilised without any problems.

• Absolutely realistic tree stump design
• Very easy to clean, for better terrarium hygiene
• Removable egg-laying tray
• Also suitable for 60 mm Petri dishes
• Compact dimensions: 12.5 cm x 11.5 cm x 7 cm

We advise you to set up several Lucky Reptile Frog Cave spawning caves in different places in the terrarium: this will usually convince particularly demanding frogs and make it easier for your amphibian adoptive children to spawn.

The dimensions of the terrarium cave are 12.5 cm x 11.5 cm x 7 cm.
