HCA: Hermit Crab Association

Hello again, I believe we have a 20 gallon tank. Our substrate is about 4-6" deep, made up of 5 parts sand to 1 part ground coconut fiber. It's moist but not too moist and we spray it daily. The temperature is about 70-76 degrees with about 80% humidity and there are two 9 watt heaters on each side ...

That's too bad, the last thing we ever want to do is to be causing the deaths of these sweet little crabs. I will work on filling out the information and post it here tomorrow. I regret not having done this sooner.

Hello, I'm sorry I didn't answer all the questions before, I've been away working on my parents' house. I returned a few days ago and my husband told me that Smaller was running around without it's shell but that it was fine. At one point he found it riding on Hermie's back and he assumed Hermie had...

Hello again, I guess I'm just a worried crab mom. So I had the large crab, Hermie, and then got him three friends, whom I'll just call Medium, Smaller and Smallest to make it easy. Hermie seemed a little aggressive (or maybe he was just excited to have friends) so I removed him the first night befor...

Hello thank you for all your information! Very helpful. I too wonder why the others all died, it was really heartbreaking. In all honesty it's a lot of work taking care of crabs and my daughter had gotten one as a present in a little tiny plastic container and the person said they were really easy t...

Help...I am concerned. We had five crabs but they'd go to molt and never return so ultimately we were left with one that has been alone for quite some time. We decided to move it to a new crabitat and we did that today, and we decided also that it needed friends. At the pet store we picked up three ...

We have 5 crabs but 3 of them have been molting for 7+ months. (The other two are molting now but they've not been gone too long so I am not worried about them). I am concerned because the 3 have been gone so long. Unbeknownst to us our warmer gave out for some unknown period of time during the wint...

Thanks, that's good advice, we baked the sand as well so I feel a lot better about it. Thanks!

Hi there, I am moving my crabs to a bigger tank and am going to mix sand in with the coco fiber. We got a bag of play sand at Home Depot but it is very moist. It looks perfectly clean but do I need to rinse it with dechlorinated or salt water? I am thinking they probably rinsed it with tap water tha...

Good to know, thanks! We ended up ordering a solid top for their aquarium and just put it on about 15 minutes ago and it's already really helping the humidity level. I'll check out about the shells as I'm not sure the ones I have are right, or the right shape. One seems downright heavy, perhaps only...

I'm hoping to get a photo up soon. One of them came out and walked around so that was good. Some other urgent matters came up but I'll report back soon. I'm also thinking about getting a few more shells, I know one tried on a bigger one but I guess decided it didn't like it so switched back into it'...

Thanks. I'll see if I can get a photo in there another way (and see how to make one for my profile picture). It's true, maybe there are active and I just don't see it if it's at night. I'll have to go check on them some evenings in the middle of the night and see what's up. Thank you, and to everyon...

I'm going to try this again:

Here is a picture of my crabitat, maybe if it works, trying to figure this out so bear with me!

We lose a lot of moisture through the top of the tank (screen cover) so we have towels over it but we're going to order a better lid. Should we get an all glass lid? I'm assuming we need to have air holes though for circulation and for them to breathe, can anyone recommend a proper lid?
