FLUKER'S HERMIT CRAB FLAT STICK ON THERMOMETER.
Fluker's Flat Thermometer helps you establish an appropriate Environmental
Temperature Range (ETR) within your pet's enclosure. (78-82 degrees F for most
Hermit Crabs) Fluker recommends using two thermometers mounted at opposite ends
of the enclosure to help you monitor the ETR regularly. Directions: Attach
thermometer to the inside of your Hermit Crabs enclosure.
