HCA: Hermit Crab Association

Yeah, we removed the bodies, cleaned the tank and boiled all of the empty shells.

Hi, our 3 crabs had been doing well in there since 2019. once we figured out the correct substrate, temperature, foods, waters and other features there seemed to be no issues that we couldn't fix. If they got ants or algea, we cleaned it out and they were OK. None of those things have happened in a ...

Thanks for the replies. One of our crabs (the smallest) was bought weeks later than the others. It is the one that molted. The other two may be molting I guess, but it's hard to tell. I knew it was a risk to dig them up, but they had been underground a long time with not enough sand and poor quality...

OK, we've had 3 crabs since summer. At first our aquarium was probably not that great for the crabs, and they eventually seemed to stay below the sand all the time and never move. With the advice and information found here, I was able to make the tank conditions better. After several months of NO ac...

Hi Again. • My enclosure is fairly sealed now and always has at least 80% humidity according to the digital hygrometer. • I've been providing the crabs with lots of protein and other recommended foods. and all of the other upgrades to their habitat previously mentioned BUT These crabs still wont com...

OK, I've put some of your recommendations to use already:

• Added some moss in the enclosure

• Adjusted the lid to fit better/tighter

• Wet down the sand for a better "sandcastle" consistency

• and was sure to get them some more fresh protein!

Thanks again everyone. When you say shell-based sand, do you mean Calcium sand? Do you have a bag or box that it came in? Also, a 'hill' isn't appropriate, substrate needs to be deep all over the tank. You can have a 'slope', but even at the most shallow area of the slope, it needs to be at least 6 ...

Thanks for all the tips. I'm sure they'll help at least a little! What is defined as "Medium"? I'd guess these guys are roughly 2 inches square. Is that "small"? The other one we got from a pet store is a lot smaller. Maybe 1 inch. Should I spray some dechlorinated saltwater or freshwater into the e...

Hi I'm new to hermit crabs. I've learned a lot on the internet about their care, but came here for more specific advice: My concern: My 2 medium and one small crabs spend ALL of their time underground in sand burrows. We even smoothed out the surface sand so we could see their footprints, if they ca...
