   Watermelon Crab Care Red claw crabs need a tank with a secure lid because they are climbers and can easily escape. You should have a tank that is 10 gallons minimum. Red claw crabs will pinch with their claws, so you should always use a net when handling them. They prefer water with neutral to slightly high ph, and with a temperature range from 70 to 85; be sure not to exceed 85F. Large red claw crabs have a tendency to rip up most plants, but you can try using Java fern in the tank.  Rocks, bogwood, and caves are good for red claw crabs to burrow in. Air stones will help keep your water oxygenated. Light colored sand is great for their substrate, and it will allow you to better see your red claw crabs. Although crabs are scavengers, you still need to keep the water well-filtered, and change the water regularly. Watermelon crabs are nocturnal, but they should have around 10 hours of sun or artificial light per day. Watermelon Crab Diet Red claw crabs are omnivores, and will eat a variety of foods. They eat meat, such as brine shrimp, bloodworms, dried fish, and pieces of earth worms. They will also eat fresh vegetables such as peas, cucumbers, spinach, etc. You can feed red claw crabs a wide range of packaged foods, such as algae flakes, shrimp pellets, and fish flakes. You can also give red claw crabs extra calcium in the form of eggshells, cuttlebone, or cuttlefish. They will eat their own discarded exoskeletons for calcium as well. Adding sea salt to their water will help provide Watermelon crabs with extra minerals. Watermelon Crab Molting Watermeloncrabs molt in fresh water, but a little iodine in the water will help reduce the risk of death after molting.  It also makes the conditions for molting more ideal. They will molt every three to six months, and will remain buried in the substrate for several days when molting. Once their exoskeleton hardens, they will surface.  The crab may eat its own exoskeleton after molting, so you should leave it intact until your crab eats what he wants of it.  Molting is a stressful time for crabs, and you should not bother them while they are molting. Watermelon crab Behavior Watermelon crabs are sociable, and they will do well with other Watermelon crabs. Males are territorial however, so don’t put more than one in your tank.  Mudskippers, gobies, guppies, mollies, and other non-aggressive fish make good tank mates for them. Red claw crabs will spend a lot of time digging, burrowing, and climbing on and in rocks, caves, and wood. They are attractive crabs and look nice in hobby aquariums. Special Notes Watermelon crabs are relatively easy to keep, but make sure their water temperature is properly maintained. Red claw crabs seem to do better in slightly brackish water, so adding a small amount of sea salt to the water is recommended to provide them with minerals and make conditions better for molting.
