HCA: Hermit Crab Association

Okay, thank you so much! So far one of my crabs has already come up from his very successful molt. 😁 Now that I know there in no such thing as “too much humidity,” after I re-wet the substrate I can continue to mist it to ensure it won’t dry out! Thanks again, and hopefully Mango (my other molting c...

So I moved the hygrometer up higher and it still reads normal humidity (in the 80’s). I checked to make sure all of my heating pads are above the substrate (they are) and still no sign of the other two crabs. If I add water to my substrate the tank humidity will be in the 90’s. Is too much humidity ...

I actually just had a revaluation as to what the problem could be! I have been keeping my hygrometer on the sand in the middle of the tank pushed up against the glass. The crabs always knock it down so it gets covered in sand. Could this be making it read a higher humidity than what the air actually...

Is it safe to pour water onto the sand while I have molting crabs? Should I wait until they are done or is it more dangerous to have dry sub? Also the air humidity is perfect right now but once I add water to the sub the tank will probably be too humid. Maybe in the 90’s for percentage. Is there suc...

I think you’re right about mostly just the top being dry, because when I pulled the chopstick out the hole only filled up halfway. Which I assume means that the upper half of my substrate is completely dry and the bottom half is moist.

I just calibrated it and it is 4% too high. So it’s not very far off. I don’t understand why my substrate is so dry when my tank is around 80% humidity. Maybe it’s too much sand? But even if the ratio of eco earth to sand was off, I still don’t think it could have such a drastic effect. I still have...

My hygrometer says 88% right now and I havent calibrated it. My lid is glass, though it does have a small gap. How can I effectively calibrate my hygrometer? Now that I think about it, it is suspicious that I haven’t had to mist my tank and it stays humid but the sand is dry… Now I’m worried it’s in...

My tank is 29 gallons and I have three pp crabs with about 6 inch deep sand and eco earth substrate. Though it may have too much sand? No matter what I do, my substrate won’t retain moisture. At first I thought my heating mat was too low, so I moved it up above the substrate and used a whole gallon ...

I love that video! So sad how the spy didn't end up with a shell! :c Lol!

When I first got my crabs, I was panicking thinking that they were going to die because they weren't eating or drinking! But, we as humans have to remember that these animals know how to survive without us lol. So they definitely are eating. :) Also, if you haven't already, I would check out the car...

So You think I should isolate her even though she is done molting? Or should I just keep a close eye on her and wait until I see any aggression or anything- then isolate her?

Update: So I actually didn't isolate her in a container because I was worried that I would stress her out way too much, so I put up barriers on either side of the Tupperware she was behind. It seems to have worked very well, other than she escaped! Yeah, now I'm confused- I thought this girly was ha...

Update: I think the reason she chose to do a surface molt is because the lid I had underneath the Tupperware water bowl was making it so she could not dig down. So I moved that out of the way and I hope she will start to dig now! She has actually molted really fast and now it looks like everything i...

I'm have containers from the pet store that already have holes in the lid so I can put her in that, though should I just put it on top of her with it upside down or scoop her into it right side up? I can try to post a photo, though it's a little confusing but I will figure it out. It is the next day...
