HCA: Hermit Crab Association

We purchased two hermit crabs from a beach store while in Florida on Wednesday. We had no idea what we were getting into until I came upon this website. Based on your recommendations, I bought all the necessary things from Amazon for them but they will not arrive until Sunday. Right now I just have them in this plastic container with a lid we got from the store. Will they be ok in there until then? Is it best to keep them indoors or should I keep them outside since it’s hot and humid (we’re in Georgia)?

I would at least try to keep humidity at 70% or above to protect their gills. Keeping them outside (out of direct sunlight, it’ll heat up their container like a greenhouse) may work if it’s humid enough, otherwise you can wrap the lid in plastic wrap to hold in moisture.

Thanks. It’s 79% humidity outside and 81 right now. I’ll put them on my deck for now.

If you can keep their tank at 80 degrees and 80% humidity they’ll be fine.

Welcome. Good luck

What kind of plastic container? Like a Tupperware container? A critter keeper for kids that's 2x height of shoe box? Maybe it has vents or lid?

Glad your in Georgia's. Sounds perfect climate for them.

Cover the basics for now. Food, fresh water, hermi crab safe salt water, temp/humidity almost a given for your climate, place to hide, and any amount of safe substrate you can.

Maybe bring it at nights for now. Try to get them at least 2 shoe box size container. Tupperware, plastic tub, bucket, ect. Standard practice to cover lid so crabs dont get out and to keep humidity in. Can cover with loose plastic wrap like substance. Can use tiny plastic dishes
