[Top 5 Picks of 2020] Best Hygrometer For Hermit Crabs

Hermit crabs rely on the environment to regulate their body temperature because they are cold-blooded. Ideally, you would want to maintain their habitat temperature at 78 degrees F and their humidity at 80%..

When the temperature of the Hermit crabs is properly regulated, they stay active throughout the day. When the humidity and temperature are right, the hermit crabs will burrow, dig and climb more effectively. 

You have to get the habitat right from the start because it means the difference between life and death. Hermit crabs have modified gills that require moist air throughout.

When the humidity falls to a point below 70%, they start suffocating slowly and the gills dry out.
