Red Chili Crab History
Red chili crabs originate from Taiwan, Hong Kong, Indonesia, and the Philippines. They are typically found several miles inland along rivers and in mangroves. In aquariums, they live in freshwater, but they must also have terrain in the aquarium as well. They will only reproduce in brackish water. The red chili crab is also called red flower crab. Their bodies are reddish orange in color, and their legs are brown to reddish. The red chili crab’s claws are cream colored. They have flattened bodies and protruding eyes.

Red Chili Crab Care
Red chili crabs need a well-structured aqua terrarium with a secure lid because they are climbers and can easily escape. You should have plenty of rocks and pieces of wood in the tank for them to climb on. Potted plants are a good option as well because they can be easily replaced if the crabs tear them up or trample them. They like to tunnel, so a cave or something they can tunnel through is a good idea. A good, sandy substrate will provide them a place to dig, and they will bury themselves in it when they molt.

Red Chili Crab Diet
Red chili crabs are omnivores, and they will primarily eat algae and organic matter in the tank. However, you should supplement their diet with vegetables like sprouts and zucchini, as well as apples, pears, and bananas. They will eat mosquito larvae, chopped earthworms, sardines, tuna, and mussels as well. They will eat most any dry food, such as fish flakes, shrimp pellets, or dried algae flakes. You can also give them cuttlebone or crushed eggshells for extra calcium.

Red Chili Crab Molting And Reproducing
Red chili crabs molt and reproduce best if their water is slightly brackish or salty. Adding sea salt to the water will help. They will molt every few months, and will usually eat their own exoskeletons after molting. Breeding is not usually successful in captivity. If the female gets pregnant, she will carry hundreds of eggs for three or four weeks. Once the eggs are released, the offspring will go through several larval stages before appearing as miniature adults. The offspring are considerably at risk from predators during the larval stage.

Red Chili Crab Behavior
Red chili crabs should be kept in groups. Each group should ideally consist of three or four females and one male. The males are territorial, so more than one male in a tank can equal trouble. They can have non-aggressive fish as tank mates. They are great climbers, and they will spend considerable time digging and climbing. They are attractive looking crabs for a hobby aquarium, and they are easy to care for.  

Special Notes
Red chili crabs are relatively easy to keep, and they are entertaining to watch. Although they live in freshwater, some salt added to the water provides them with needed minerals, and is beneficial for when they are molting.
