HCA: Hermit Crab Association

A few degrees of change isn't going to make a huge impact. When you get up to around a 10 degree difference then it gets iffy, as I have found that mine do choose where to molt based on temps and I personally do everything possible to prevent wild swings.

They are so uniform that it's interesting! I would guess fruiting bodies of a fungus? They also look like insect poop of some sort, but I'd think you'd notice whatever was doing it if it was.

(Also, really nice macro skills!)

Yeah, it'll be fine with just water, or soap and water. In an emergency I use the ones I have in the cupboard for leftovers.

He needs isolated. Rinse him and a few shells off with dechlorinaged water and put them into a small container, like a tupperware or clean margarine tub.

You're seeing shed exo laying against the bottom of the whole, so he's molted and is now regaining strength and slowly eating his old skin. They do go into a kind of stupor/sleep while molting and may not move much or at all for long stretches. It conserves energy as they harden back up, because the...

I would leave them all in there then! There will be so much more stress from moving them around, then a little low humidity will cause overnight.

Unless you are an expert in identifying lichens, I wouldn't recommend it. Some are poisonous, and no one here will be able to help you figure out what is edible and what is toxic. Mosses found outside should be safe, but they will absorb any chemicals or toxins they have been exposed to - including ...

They should be okay to stick together if you're worried about a power failure and it getting too cold. Individual cups would be safer, just because they can get scared and panic, and hurt each other by accident. Honestly, if you have any fears of loosing power and the temperature in the house droppi...

Ultratherm and Fluker can for sure be safely insulated. I'm not sure about others, but if they are laminated with clear plastic and very flat they will probably be safe - they'll come with instructions (you can even usually find PDFs on the manufacturers website) that will tell you for sure.

Okay guys. Thanks! The link provided above, isn’t bringing me anywhere, it’s saying 404 page error or something like that. But I’ll do some searching on google and see what sites and articles I can find providing info about ants and how to keep them away from my little hermits! I’m so happy I decid...

This is from an ant keeping forum on how to keep them in, but would also work for keeping them out - while also being harmless to hermits. https://www.tapatalk.com/groups/antfarm/the-beginner-s-guide-to-ant-keeping-t13211.html https://uploads.tapatalk-cdn.com/20191215/d57f8430ff15c52ece0c0de1641a0f6...

It's normal for them to go through periods where they don't move when molting. I think he's fine! He shouldn't come up for a while though - I wouldn't start to expect him until sometime in February, and he could go longer than that.

@CrabbyLover77 Does your vet take in arthropods? If I tried taking a fiddler crab to any of the vets near me I’d probably get turned out. Sent from my iPhone using Tapatalk Having a good relationship with your vet helps! Most have zero training on exotics, and while some won't see them because they...

It's a little unusual for new crabs to not molt in that period of time. Crabs that are the right size for a 10 gallon should also be molting every month or two, so I'm a little concerned about how big yours are? They will put off molting of they don't feel safe enough - they have to be underground a...

Either way, it sounds like might loose the limb. That shouldn't harm him, they're very well adapted to losing their claws. If it does occur, the opposite claw will become the large one on his next molt. I'm not sure I would try to remove it, just because they are extremely hard to handle and you don...
