The Australian Land hermit crabs (Coenobita Variabilis) are a species of terrestrial hermit crabs indigenous to Australia. They are nocturnal omnivores, thriving in tropical regions in close proximity to water bodies.
These specimens exhibit a range of sizes and appearances, spanning from a pale sandy hue to reddish tones and varying in dimensions from that of a thumb nail to a tennis ball.
As Arthropods, hermit crabs undergo molting as a necessary process for their growth. They exhibit behavior where they burrow deep into the substrate, construct a cave, and remain secluded until they shed their exoskeleton, allowing their new exoskeleton to harden.
Upon reaching a certain size, they are compelled to seek out a larger shell to accommodate their growth.
Land hermit crabs have the ability to respire on land through their adapted gills, which enable them to absorb oxygen. This process is dependent on maintaining high levels of humidity, as inadequate humidity can lead to desiccation of their gills, ultimately resulting in suffocation.
Despite the moniker 'Hermits', hermit crabs exhibit highly sociable behavior and derive pleasure from the companionship of their fellow species. In their natural habitat, they frequently form sizable colonies.
When caring for land hermit crabs, it is essential to provide them with companions to prevent loneliness.
Despite being marketed as 'easy beginner pets', the reality is quite different.
The Australian land hermit crab necessitates a specific and meticulous environment for its well-being. With proper care, these creatures can thrive and live for up to 15 years in captivity.
It is recommended to provide a minimum of 38 liters of tank space per hermit crab, along with at least 6 inches (15cm) of substrate. This allocation ensures that each crab has ample room to thrive, while the substrate depth supports safe moulting. For substrate composition, a blend resembling the natural habitat can be achieved by mixing play sand and damp coir peat in an 8:1 ratio.
To ensure the well-being of your crabs, it is necessary to provide two distinct pools in the tank - one with marine salt water and the other with fresh water for drinking and bathing purposes. These pools should be sufficiently deep to allow the largest crab to fully submerge itself, including its shell.
Prior to using any water in the crabitat, it is essential to treat it with a water conditioner like Seachem Prime.
Ensuring the well-being of hermit crabs necessitates the provision of a tropical habitat, which includes maintaining appropriate levels of heat and humidity.
Ideal Temperature Range: 26°C-32°C
Optimal Humidity Level: 70%-85%
One method to achieve this is by positioning reptile heat mats or cords on the exterior of the tank. By incorporating deep pools, substrate, and elevated heat, it will result in increased humidity levels within your crabitat.
These conditions can be monitored using a reptile thermometer and hygrometer gauge.
Introducing enrichment items and tank decorations will enhance the natural ambiance of your crabitat, stimulating activity and fostering a healthier environment.
