New mini crab

[stonespot]

Use a breeder partition box to keep them. Good idea? Maybe can do a super nano tank using the box. No need filter, no need to worry where to keep them and becomes new tank mate for the shrimp lol.

I'll take a shot in the dark and suggest this to be Geosesarma sp. "Orange/Mandarin", which is not an aquatic crab, but a terrestrial one. So I would suggest to provide some significant amount of land area for them. Supposedly from Sulawesi (perhaps also other parts of Indonesia), G. sp. "Mandarin" is actually not new in the trade, but may be new to our shore.

Just a note of interest, Geosesarma sp. "Orange/Mandarin" has been positively identified as Geosesarma notophorum (Ng, P. K. L. & C. G. S. Tan, 1995).

However, it is still unsure if the crabs here are actually Geosesarma notophorum (aka sp. "Orange/Mandarin").

oh bro dzylim, any update on these crabs?

[stonespot]

HI I bought a set of mini purple crab but i'm not sure if they are the vampire mini crabs. Orange eyes, purple claws, purple/black/orange light shell. When crawling it's slightly bigger than a rummy nose. But it can stretch to at least 5cm with its legs when trying to climb over the container. The female is bigger than the male.

Probably Geosesarma notophorum. They are semi terrestrial crabs. Don't put them under water, they will drown.

I just bought a container for the vampire crabs. The container shape like a liver swimming pool and it has an island in the centre with a fake coconut tree. I filled up the tank with 1 inch water and they are swimmining happily in there for hours. I pushed them onto the island but they still prefered the water.

Let them be. Maybe they are scared of you and that is why they are hiding in the water

Wow, looks like quite a few people getting into crabs nowadays. I wonder if they're good with the fishes. Will they attack cories?

i don't think they are 100% submersed. they may drown in your cory tank..

Mum mum what's that thing in the CRS tank..... A boy shouting to his mother... Then the boss spoke in a very low tone " That's the latest Mini Crab" in Mandarin.
(What are you waiting for) While stock lasts.... That little boy just bought 1...hours ago.

Price - Same with Sulawesi Cardinal. Really crazy cheap.

[stonespot]

wow according to the LFS, he already sold 2 batches in that week. This morning i saw left only 5~7 pcs. (male and female mixed)

[dzylim]

i still do not know the name of the crab. haha. as of now i am starting my 2nd batch. the first batch has all disappeared into some part of my house.

Hi there

Just a note of interest, Geosesarma sp. "Orange/Mandarin" has been positively identified as Geosesarma notophorum (Ng, P. K. L. & C. G. S. Tan, 1995).
However, it is still unsure if the crabs here are actually Geosesarma notophorum (aka sp. "Orange/Mandarin").

Exactly, but the crabs shown in the first post look more like G. notophorum than the very similar species G. krathing to me. Although both have a slightly different "look" they can be only identified definitely (!) by morphological details (or good photographs of these details).

They don't drown – just as "Vampire crabs" can't drown, but there ARE Geosesarma species that CAN drown, e.g. G. nemesis.

Nonetheless both need a terrarium (or aquaterrarium) with a water part. For G. notophorum a dish with fresh water is enough, Geosesarma sp. "Vampire" needs a true water part.

bro, does this mandarin crab rear its young like the vampire crab?

[BEASTIEPENDENT]

Hiho

G. krathing breeds the same way as the "Vampire crab". G. notophorum has another form of brood care: After hatching the younglings are taken for two or three days on the carapax of the mother – a behaviour not known for any other Brachyuran crab. But both reproduce easily in a terrarium with fresh water. They don't have pelagic zoeas larvae.

thanks bro..

could you post a pic of their setup?
also what kind of substrate is best for them?

[BEASTIEPENDENT]

Hideho ;-)

Sure, which one do You mean? I post all.


Geosesarma notophorum, 30 cm cubicle, 5 specimen:


Geosesarma krathing, 30 cm aquarium, 2 "girls":




Geosesarma sp. "Vampire", 60 cm tank, a whole "family":


Geosesarma sp. "Blue" (also called sp. "Yellow Eyes"), 40 cm tank:



As substrate we always advice "terrarium humus", that's pressed rainforest ground. Sand or soil usually starts to foul and get moldy. Terrarium humus accomplishs best with moisture and food remains – and the crabs can dig in that substrate. Since it can always be moist it is also good for the climate in the tank which should contain high air humidity.

Seeing as there's been no activity on this thread for 2 and a half years, this is merely a shot in the dark: Would anyone here be able to direct me to a supplier or endemic habitat in Peninsular Malaysia or Singapore where I might find some of these mini crabs?
