The Zoo Med Hermit Crab Heater is a specially designed adhesive heating pad created to provide the optimal ambient warmth required for hermit crabs to thrive. This UL listed, four-watt heater is ideal for use with plastic “keeper” type cages and small terrariums, making it a crucial component in reptile lighting and heating setups. The heater gently raises the temperature inside a hermit crab habitat by about two to eight degrees Fahrenheit, maintaining the ideal range necessary for the crabs' health and natural behaviors, especially important for their molting process.
Designed to be slim and compact, it can be attached either to the side or underneath the enclosure. Moreover, the heater includes bump-on feet that help elevate the tank slightly when placed underneath, preventing excessive heat buildup and ensuring even temperature control. This reliable heating solution helps create a more natural environment, enabling hermit crabs to maintain their activity and metabolism optimally.
