Hermit Crab Environment tools: what they help with
These tools check the conditions your hermit crab lives in: temperature and humidity ranges, lighting distances, heater sizing and other habitat numbers. Many hermit crabs cannot regulate their own body temperature or humidity. When the enclosure is off, health problems follow, often slowly enough that they are missed.
What to know about environment and habitat conditions for hermit crabs
Hermit crabs are social colony animals needing at least 15cm of damp sand to bury and molt in, plus both fresh and salt water dishes and many spare shells. Most deaths trace back to too-shallow substrate. Target humidity is around 70-80%.

A practical tip
Measure with a digital thermometer and hygrometer at the animal's level, not near the heat source. Readings a few centimetres apart can differ a lot.
