Hi got more crabs.

Only have their trade names. Anyone know the scientific names?


Goes by the trade name Fire crab. Totally aquatic. Around palm size



Orange crab, probably Geosesarma sp, only 3 cm across.



Under trade name Red apple crab. This is double the size of Geosesarma sp Vampire.

Great looking crabs you've got there. Thanks for sharing. All the best for finding out their scientific names

BTW, where did u get these crabs?

Good morning

The first one I can't identify yet. The highly inflated branchial regions usually mean it's a land crab. Funny that this one seems to behave aquatic – or is this just an information of the supplier? Does it hav possibility to get out of the water?

The second should be Geosesarma notophorum, a highly terrestrial fresh water Sesarmidae. Possible would be also G. krathing but they are hard to differentiate, anyway I'd say it is G. notophorum. If the females carry their younglings for two to three days after hatching on their backs You're sure it is G. notophorum.

The third one – sometimes called Apple crab – is Metasesarma aubryi. Though it reproduces like traditional Sesarmidae with larval stages in the sea it is highly terrestrial near freshwater streams. Does not like water, but does not drown.

The first crab is totally aquatic, stay in water 90% of the time. Only come out of it occasionally or after I change water.

Thanks so much for the id Beastie.

Hi Lucas, you might want to try Jakarta.
The only one i have seen so far is in C328, they do have some of the orange crab

You're welcome

Can You take some more pictures from the first crab? Important would be carapax from straight above, face, mouth parts, scissors from different perspectives, pleon, walking legs (especially wether there is a "tooth" at the distal end of the first segment)… If possible You can E-Mail the pics in highest possible resolution, my mail box has no MB-limit.

[joydiv]

I will but I dont think I can email big files so probably i will host it on my photobucket.

Thanks again so much.

just to ask are crabs generally hard to rear??

thinking of rearing some in a 2ft tank. is that enough?

[joydiv]

These crabs are quite easy to keep. They are mostly land crabs but they do need a water source to keep their gills chamber wet.

Food wise, they take small size fish pellets as well as fruits.

A 2 feet tank is big enough, you can keep around 2 to 4 pairs in it.
