Because of its very broad carapace and the hairy legs this crab might well be a Xanthid crab. Similar are crabs genus Lachnopodus. The appearance is similar to Lachnopodus tahitensis., but we are not sure.
An other identification send us MaxOrchard (Christmas Island) ""....my associates from Lee Kong Chian Natural History Museum in Singapore have replied to your enquiry....
The crab does look like a Lachnopodus… probably L. subacutus (Stimpson, 1858). Hard to see some diagnostic features from the photos alone."
Many thanks for the helpfull answer to Mr.Max Orchard and his associates from Lee Kong Chian Natural History Museum in Singapore !
The most Xanthid crabs are more carnivorous or even predatory so everything that'S small enough to fit into the pincers will probably be eaten. You can try any sort of frozen food like bloodworms or mussels or fish and also flake fish food and so on. Maybe it takes algae too you can try. Should be no problem to feed that crab. Might be you can feed it even with a pincer.
Genus contains the following species:
