White Arm Crab History
White arm crabs originate from one of the largest islands in Indonesia, Java Island, just south of Borneo.  They are freshwater crabs, and are usually found in swamps or marshes. In an aquarium setting, they need land as well as water.  The bodies and carapace of the white arm crab are dark brown to black. Only its scissors are white, and that’s how they get their name. White arm crabs have black eyes. Males have hair on the last third of their claws, but it is not easily visible.

White Arm Crab Care
White arm crabs are easy to care for, and they typically reproduce well in captivity. Their aquarium should be layered, with a large area of freshwater as well as plenty of terrain for them also, such as rocks and pieces of wood. Plants are good for them to climb and sit in as well. They will frequently sit above the water and dangle their legs in the water. The water temperature should be in the range from 68 to 82F, and the tank environment should be humid.  You should change their water once or twice a week so that it will remain clean and fresh. They will do well with other white arm crabs in the same tank, but be wary with much larger or aggressive tank mates.

White Arm Crab Diet
White arm crabs are omnivores. They eat meat, such as brine shrimp, mosquito larvae, cyclops, and pieces of earth worms. They will also eat fresh vegetables and apples, pears, bananas, etc. You can feed white arm crabs a wide range of packaged foods, such as algae flakes, shrimp pellets, and fish flakes. You can also give white arm crabs extra calcium in the form of eggshells, cuttlebone, or cuttlefish. They will eat their own discarded exoskeletons for calcium as well.

White Arm crab Reproduction
White arm crabs reproduce in fresh water. The female carries several eggs under her apron, although in captivity the exact number varies. When the eggs hatch, the emerging offspring appear as miniature adults rather than larvae. The offspring will have all dark coloring. Their claws will not lighten until they mature. Care should be taken to protect the offspring from predators while they are very small and vulnerable.

White Arm crab Behavior
White arm crabs are sociable, and they will do well with other white arm crabs. . Ideally, you should have one male and three or four females in a tank.  However, they are small and somewhat vulnerable to predators. They will spend some of their time in their water, but more often they will sit above the water with only their legs resting in it. You should provide plenty of places for them to sit or hang.

Special Notes
White arm crabs relatively easy to keep, provided you keep their water clean and keep them away from predators. They are not the most active species of crab, but they are attractive and make a good aquarium crab because of the relative ease of maintaining them.
