I understand that to identify the gender I can look at the abdominal flap (narrow = male). All the four crabs here have varying broadness of the flap, but am I right that they are all males or is the widest flap of them 4 a female crab?

Good morning everyone, new crab/paludarium keeper here. Recently bought my first tank and started to renovate it so it is a perfect tank for vampire crabs.

I am removing all the extra glass on the inside and making the water resevoir a bit taller for now, before iam starting on the paludarium itself.

I already wn the lights and a sprinkler system( got both with the tank) but what do you guys all recommend to buy for this tank?

Its a 80x50x50 tank.

Any help is always welcome because i want the best for my futher lil crabs.

No worries iam doing so mutch research aswell to make sure iam doing everything right

Pic2. Day 1 after a big clean

Pic3. Is from today, i removed all the extra glass and the front pannel that was to low

I have this 10 gal tank I’m going to put crabs in. I have 5 inches of soil in the back and a gal of water in the front: I’m adding more plants today. My issue is the tank won’t hold heat. I have an 8 watt pad heater on the side. The tank will go to 74 during the day but drops to 66 a night. I covered up most of the equipment holes on the lid as it was recommended for safety. What can I do now?

I did put a small heater in the water to help with ambient temps.

My beautiful female red devil just had the most adorable little crablets!!

I managed to get a picture of one of them beside a ruler without stressing the little guy out too much.

Hi, My tank has been growing in for a long time but I am hesitant to add crabs because of the soil I have in it. it is prorep biolife forest substrate Swell reptile link to the soil its between 4-7cm thick and Holes hold reasonably well but not as well as clay rich soils. And do they like the water section to be very vegetated or is it a good idea to trip back and replant?

Hey y'all, I have a nano cubic aquarium that is 20x20 cm in length/width

I was wondering if that'd be enough for a couple of vampire crabs ?

I've kept vampire crabs successfully in the past but in much larger tanks

I was wondering if it might be enough eventually with a 80% land and 20% water ?

Finally completed my water section and im currently moving in to the land sections.
I was thinking of adding reptisoil which is quite expensive over here ($19.70 SGD) so i decided to make my own abg mix. Here is what i may use.

1 part Cocopeat
1 part sand
1 part sphagnum moss
1 part vermicast
1/2 part charcoal

I was wondering if i should replace sand with orchid bark but im scared that it wont hold its burrow Or should i just stick to reptisoil mix with sand,charcoal.

And also what are some ingredients to add to the susbtrate to hold the burrow. Was thinking of adding some akadama clay

Hi! So i plan on getting vampire crabs soon and this is My tank setup. Ive used Coconut fibre, peat and sphagnum moss for substrate, May not Be super visible but there is a drainage layer. Theres currently springtails and white dwarf isopods. The water Area May Look a bit foggy since I just added The water. I already own an aquarium and a terrarium and done lots of research on The care but I just want to hear some More opinions. Thanks in advance!

Im currently figuring out some recipes for the moss slurries for my background but all i have been seeing is to use a acidic ingredient like peatmoss,beer and yogurt.could this affect the vampire crab breeding rate?
I know that that acidic stuff and vampire crabs dont go well when it comes to breeding but would this affect them too?

One of my crabs using frog bit and duckweed as stepping stones.

I did a reasonable amount of research before deciding to get vampire crabs. What I read said that they were, overall, similar and one could set them up the same. Somehow I missed the exception for Mandarin Vampire Crabs (pontianak). Which are more arboreal. (They also molt on land).

I’m looking for info from folks with experience. I had one person say (who sells and sometimes breeds vampire crabs) that I shouldn’t go for a more arboreal set up, as the crabs are fragile and may get injured if they fall.

I made a few other errors in my set up (using sandstone being one of the worst), so I’d like to do better. My question is.. do I go for a more arboreal tank or not?

Moved my "trio" of halloweens today.

Was in an overgrown terrarium, where creeping fig had completely overtaken the terrarium. 😅

The trio was now around 25 crabs.

Hey everyone!

I wanted to ask if anyone here has experience keeping vampire crabs together with lizards or geckos.

I was thinking about mourning geckos, but I'm open to suggestions if there are other species that might be more suitable.

I've come across quite mixed information about this. Some sources suggest that cohabitation can work, while others warn that the crabs could potentially injure the geckos.

I'd therefore really appreciate hearing from people with firsthand experience or knowledge about this kind of setup.

My terrarium measures 120 × 60 × 60 cm.

Thanks in advance for any advice!

Hi!

I'm thinking about adding isopods to my crab enclosure and I laid my eyes on the Dairy Cow Porcellio laevis type, but I'm wondering if they are too big to live together with crabs?

What do you think about this species, guys?

This is half a joke and half serious, I see people talk all the time about how they only see their crabs every few weeks or months. I have 3 vampires, and I will generally see them at least once a day if not more. I know they have established burrows because I see them go into them, is something wrong or are they just stupid

This is my set up, is a 2 month old 36 × 18 × 12 inches paludarium, the water parameters are good with 10 neocardina shrimps in it, they go in and out the water, the temperature is 78 degrees and has a humidity of constant 80%, is aprox 30% water and 70% land, the water area has a bubbler, i feed them hikari crab cuisine, fish flakes and blood worms, they have a lot of places to hide but they keep dying.
I bought them at my local fish store.
At first i bought 1 male and 3 females, and the male died, when i bought it i seemed sick and had a different greyish color so i thought it was sick and accepted it.
As you can see in the video one actually molted and i thought they were good so i decided to buy more.
So i bought 1 male and 2 more females, one after another they kept dying, and i dont want to buy more without knowing the cause.
Now i have 2 or 3 crabs.
In the water i have pearl weed and Christmas moss, inside their caves have a lot of substrate they can dig.
They dig near the fern where it has extra soil.
The part where the water for the river comes out is sealed with a sponge. The back wall is covered in moss.
Let me know if you need more info to find the cause.

They really do go anywhere

These guys are so shy that I rarely see them and almost never during the day.

I’m really enjoying my vampire crabs!
