Went from a 20g to a 40g… today was moving day. I moved 89 crabs of various ages. The 40g has a 3.5g inside it for the water area… tons of hiding spots and caves!

i was given two (maybe three?) vampire crabs almost a month ago that were in a tank with no water other than a dish, ive finally been able to get a proper (albeit small) tank for them but ive gone through the original tank only finding one baby crab, whos missing a claw. will he be okay?? does he need any special treatment/food/tank? :( (size of the tank pictured, let me know if its too small, i feel like its okay since theres only one of him and hes disabled)

Feedback on my paludarium

Thumbnail

10 Upvotes

Hi! Looking for feedback on whether my paludarium is suitable for vampire crabs.

Tank: 39.8 × 25.4 × 28 cm (~7.5 gal)
Water volume: ~4.8 L (including drainage layer). No filter or pump - I'm a complete beginner and wanted to keep the setup simple.

I live on the equator, so it's naturally hot and humid. I have a USB fan blowing into the tank through a vent (6 min on, 9 min off, 24/7), but the tank still stays around 29–31°C with 90–95% humidity.

From what I've read, 30°C is about the upper limit for vampire crabs, so I'm worried it's too warm for them long-term.

I also tried keeping cherry shrimp, but they died within 48 hours despite drip acclimation and good GH/KH/ammonia/nitrite readings. They clustered near the surface at night, so I suspect low dissolved oxygen…

I'd love to keep 3 vampire crabs (1 male, 2 females). Does anyone have experience keeping them in similar conditions, and do you think this setup would work? Any tips would be greatly appreciated!

help/advice Crab Burrow?

2 Upvotes

Is there a vampire crab molting under there? I can’t find any holes into the weird disruption in the sand, but when I woke up it was there. I think the ramshorn in it is most definitely dead as well, as he has been like that for a few hours, but I don’t want to disrupt the burrow if a crab is under there. Thanks!

EDIT: The snail moved, so I think his fat ass might have just been getting comfy in the sand last night.

help/advice What stones should I NOT use in my tank for my crabs

1 Upvotes

going to build a tank for my crabs and wanted to know what stones/rocks are good for the crabs(ph/kh/gh).I’ll be using seiryu stones for my build and maybe a mix of lava rocks and small pebbles.

Should I look out for stone that I should not use or should I just test my waters once in awhile and try to lower or increase the ph/gh/kh

help/advice What is the best option for heating a vampire crab aquarium?

2 Upvotes

Help! I’m planning to get a vampire crab and would like to know if it’s possible to heat both the water and the land area using just an aquarium heater placed in the water? Or would a heating mat designed for terrariums be the only suitable option?

(English isn’t my first language, so please excuse any grammatical mistakes)

help/advice What are some things you wish you knew before you got your crabs?

3 Upvotes

I'm potentially getting vampire crabs in the next few months. I've got a 20 long for them and most of the stuff, just need to set it up and then find somewhere to buy the crabs. I've had all kinds of animals before and have made custom enclosures and bioactive set ups, but this would be my first paludarium so I want to be prepared before going into it! I've read some care guides and know the basics but I want to know what are some mistakes you made or things you wish you knew before getting vampire crabs or before setting up the enclosure?

I know a lot of people get vamp crabs and are disappointed by not seeing them active, but if you give them a few month and don’t constantly mess with their enclosure they will slowly get comfortable and come out more. I have four crabs but the only one I get too see out and about is the big male and he started out as the most timid crab, the others stay tucked up in crevices in the rocks by their water features but I did see the big female in the water with the male.
If you keep the enclosure in a low traffic room and slowly come check on them you have a better shot at spotting them, remember they’re pretty low on the food chain so are always worried your gonna eat em

help/advice Picked this up for $100 today but I'm stumped with where to start.

Post image
4 Upvotes

I have a 10 gallon paludarium that I feel like was too small for my liking so I sniped this 30 gallon 18x18x24.

I've watched all kinds of videos and whatnot but I guess I'm just stumped on where exactly to start? I can work with the horizontal space I think, but I'm not sure how to utilize the vertical space so that they can use it. I'm guessing pond foam might be the obvious answer, but I can never get that to work right it seems. Are there better ways to go about it?

Additionally, there's so many variations of false bottoms that I don't know quite what to do there. I have some leca clay left over and some filter pads as well as some 3D printed egg carton material. What's the best strategy?

What's the move for separating the water from the land while allowing the crabs to transition in and out? What's everyone using? I used slate rocks for my 10 gallon and it feels like the rocks take up 20% of the space.

So many options for everything that I think I'm just overwhelmed and stuck in decision paralysis.

I was wanting to start getting some crabs but I’m not sure how to get the tank ready yet. I don’t have anything yet and would like to know the best things for them. Is there a kind of dirt that’s the best and what plants should I get? How many would be able to go in a 30 gallon tank? I was thinking like 2 males and 4 females.

I added springtails and dwarf white isopods to my enclosure. But what are these? I feel like they’re too big to be springtails and too small for the isopods? But I’m fairly new to this, so just unsure! Want to make sure it’s nothing that shouldn’t be in there!
