HCA: Hermit Crab Association

Hi, my crabs are set up in a cooler room in the house and during the cold snap things got very dry in the room. In the crabs enclosure the humidity was down to the low 60% for a day or two, refusing to budge back up for more than an hour no matter how much i misted.


Both of my crabs were (and still are) molting underground. Does anyone know if the humidity is pretty constant down there? Are they fine? I’d assume they would be safe from the small drop but i was wondering what y’all think.

I would think they would probably be okay. But there really isn't anything to do other than wait it out until they come back up.
Did you get the humidity back where it should be?

Yes, and now that it’s a little warmer it hasnt been as bad. Humidity yo-yos between 75 and 85 throughout the day.

75 and over is great!
