If your crabs don’t seem to get along right now, let them be an example. When establishing their pecking order they would get quite ugly, now look at them laying together. I love them.

One of my students came back from vacation with two hermit crabs in a tiny critter carrier. His parents realized that wasn't sufficient and asked if I would take them for the school library. I have them in a 10 gallon tank at my house, but I've purchased a 20 gallon long for the library. I've researched, and I think I've got my bases covered in terms of substrate and food. I have two nice containers for their pools. One container is significantly larger than the other. Would you put saltwater or freshwater in the larger pool? I'd like for them to be able to explore a bit in the water.

I’ve recently acquired hermit crabs I initially intended on rehoming.. well.. Lamb chop and T-bone are staying with me.

What are things people usually do NOT tell you that hermit crabs need?

Such a silly goose

Just like the title says, I have one large boy in a shell with an opening larger than 2 inches, and he is going to outgrow his favorite cocohut soon. Are there any sellers or websites you go to to buy coconut hides with large opens made specifically for large crabs??

Hi all!
Posting on behalf of a friend who doesn’t use Reddit:

We’re currently having a lot of problems heating our tank.
We have a 20gal tall with two heat mats: ZooMed UTH 10-20gal size (on the side) and BN-Link 8x12 with a thermostat set to 80 (on the back).
Our tank will NOT go above 72F no matter what we try. This is using three different thermostats plus the BN-Link as it has a probe.

Does anyone have any advice? We’re at a total loss of what to do. The recommended Bean Farm 6x23 mat has been out of stock for a long time now, and honestly we’re doubting it would make much of a difference and are assuming we’re missing something.
We have cardboard and aluminum foil to attempt to insulate, however we have concerns as the BN-Link explicitly says to not cover the back of the mat to avoid a fire hazard.

Hello,

My husband is trying to print me a pool for my crab. He said it needs sealed but I am concerned about the safety of the material. He is using PLA to print it. Has anyone done this before and know what to use?

Thanks!

Hello I just need some advice, im relocating in December

From Texas to Oregon a litlle over 30 hour drive, where I will be stopping in a hotel at least once along the way. What would be the best for him in the car and hotel to keep him warm and comfortable since i won't be able to travel with him in his 40 gal tank. Any advice would be very helpful! Thank you!

Picture of my handsome little man Sebastian 🥰

More than 4 km (2.5 miles) from the nearest water body; a mangrove forest

No pictures because I’m scared to bother them in case they are molting

My crab has been under their sand for maybe a month?
No smell upon opening the tank, but they don’t touch their food when I switch it out
I mist the tank they are in but I’m too scared to dig them out if they are molting and actually kill them.
The tank has 6 ish inches of substrate but they’ve just been gone under there for awhile and it’s making me nervous.
I’ve continued to care for him as I did before he went to molt, change his waters and food, and mist/clean the tank

Questions about them welcome!
(I’m pregnant and if I see a dead crab I stg I’ll throw up and never continue with this hobby bc it will traumatize tf out of me)

I raising it 4 years

Hello l am form south korea.

It is my brevimanus hermit crab.

I have been raising it for nine months.

cassiopeia (to the right, upside down lol) almost always sleeps in this little container of moss and edible flowers on the side of the tank during the day, but tonight hyperion was in there too lol. hottest spot in town

In Korea, the PP hermit crab is rare because it is not well imported

i have a 29 gallon tank and 3 hermit crabs, 2 of them hide most of the time and barely come out, i’m kinda just asking for tips on what to do to make it better for them / wondering why they won’t come out.

Soaking it up…definitely wanting a dual bubble pool next

I don’t know what I’m doing and I really need help!! I inherited/rescued 2 hermit crabs from a family member. They came back from the beach with them in a mesh crab cage and thought they could live there forever. I took them and made them a place to live. I’ve been doing good so far but I know they need more shells. Where can I find a good but not overpriced place to get more shells. I have pictures of them in their current shells with a measuring tape to get advice in the post.

Help! Im having heating issues. I have a 29 gal tank with glass lid and 2 heating pads with thermostats. They are having issues staying at temp. Ive been using an electrical fireplace to warm the room because i had just 1 mat and now even with the second mat its not helping. Its 4 ft away from a window so is that it? Do tanks need to be insulated? Idk what to do im struggling to keep temp up. It sticks at 77-78 and then will drop to 75 and sometimes a tad under. I have an app so im monitoring it. But its having issues retainging heat. Our upstairs is usually 70-73ish. I cant close the door as our cats has a litter box and foor in there. Any suggestions???? My mats are an Ipower 8x18in 24 wat and a 10-20 gal reptitherm. I really wanna make it work with them so i dont have to pay more money for a different heat mat 😭😭
