HCA: Hermit Crab Association

Woopsies. She is 2.5ish inches, was trying some conversions... Thanks for the info on that!
With that being said, I’m wondering if it will harm her not having another buddy or if some crabs can live alone?

Thank you

Crabs aren't as social as was once thought. What used to be thought of as 'social' behavior is now recognized more as resource sharing. So you could get another crab if you want, but many crabs have lived long healthy lives alone. The number of crabs you can have in what size tank depends on the si...

Located in central Charleston, SC. Thanks for the response!

Willing to drive 45 minutes.
I will provide supplies and the tank with the crabs.
They are not injured and have not had prior diseases.
I got them from PetSmart. I still have the documentation.

Two purple pinchers currently needing a new parent!!! I’ve had them for seven years in a beautiful 20 gal, but I am looking to move forward from having pets at this time. Located in South Carolina. Please reply on this post if interested.

Thanks for all the input! I’ve always managed to keep air humidity up but never knew to keep substrate wet enough to dig. Once I began doing so, my crabs have been so active! I’m not sure how to keep doing this with a molter, if wetting the substrate will disrupt tunnels or not? Either way, I’m happ...

Thank you so much for the information!!

Same thing happened to me. I’m going to switch back to just coconut fiber because I haven’t seen them dig down in a while. Also, they never used to surface sleep and now that’s all they do!!!

My question is: the substrate is very dry although the air humidity is not. I want to make sure the substrate (mix of play sand and...

Hi! I haven’t been able to find a solid answer on whether flash is harmful to crabs, rather than opinion. Has anyone found research on this? I like to take pictures and very rarely take videos, with flash, of my crabs. They never seem bothered by the light, but I’m not sure if they’re stunned (which...

Thanks so much. It is much appreciated.

Thank you so much!!!

Hi! I wanted to add substrate and rearrange my crabitat… I haven’t seen one of my Caribbean’s in a while, which means he might be molting.. However, I would be doing this during the day either way. So, is it safe for me to add substrate if the crabs are under? I don’t want to disrupt any tunnels and...

Any ideas on how to clean the tank glass without any harmful products? Over time it gets water spots which make my crabs less visible. I’ve tried water and paper towel, but it doesn’t work… Xo

THANK YOU!!!
