The Red Claw Crab: A Fascinating Invertebrate to Keep as a Pet
If you’re looking for a unique and fascinating creature to keep as a pet, look no further than the red claw crab. Native to mangrove swamps and brackish water in Asia, this species of crab is a popular choice for hobbyists seeking an invertebrate pet.
In this article, we’ll delve into the biology, care, and habits of the red claw crab. Learn what it takes to keep this fascinating creature happy and healthy in your home.
Natural Habitat and Background
The red claw crab, or Perisesarma bidens, is native to the mangrove swamps of Southeast Asia. These crabs thrive in brackish water, which is a mixture of saltwater and freshwater.
They can be found in a range of colors, but most often are dark brown with red claws. The males typically have larger claws than the females.
Appearance and Gender Differences
One of the most distinctive features of the red claw crab is its bright red claws, which are used for catching food and for territorial displays. Males typically have larger claws than females, but the difference is not always noticeable.
Other than this, there are no external differences between males and females.
Lifespan and Care
With proper care, red claw crabs can live up to three years in captivity. To keep your crab healthy and happy, provide it with a high-quality diet that includes both protein and vegetables.
Red claw crabs also require brackish water to thrive, so make sure to research the specific requirements for your species of crab.
Tank Size and Filtration
A 10-gallon tank is generally sufficient for one red claw crab, but larger tanks are recommended if you plan to keep multiple crabs. Make sure your tank includes a filtration system that is appropriate for marine animals, as red claw crabs are sensitive to water quality.
Use a specific gravity meter to monitor the salt levels in the tank.
Water Parameters and Heat Lamp
Red claw crabs require a water temperature between 72 and 82 degrees Fahrenheit, a pH between 7.5 and 8.5, and a water hardness between 8 and 20 dKH. A heat lamp can help maintain the temperature of the tank, but make sure it is positioned so that it does not overheat the water.
Tank Decoration and Substrate
Red claw crabs are territorial and like to have hiding spots in their tanks. Rocks, driftwood, and caves can provide hiding spots.
The substrate should be soft sand, as red claw crabs are bottom-dwellers and like to burrow in the sand.
Behavior and Aggressiveness
Red claw crabs are usually nocturnal and territorial, often becoming aggressive towards other invertebrates in the tank. They will fight to the death, so it’s important to keep them separated from other species.
In terms of tank mates, mollies, flagfish, and larger gobies are good options, but make sure to keep one male with multiple females to avoid territorial disputes.
Sleep and Upside Down Red Claw Crabs
Red claw crabs are nocturnal and will usually be found hiding during the day. Don’t be alarmed if you see your crab upside down, as this is a normal behavior during molting.
However, if your crab is upside down for extended periods or appears to be trapped, it could be a sign of boredom or stress and you should investigate the cause. Diet, Feeding, and Health
Red claw crabs are omnivorous and require a diet that includes both protein and vegetables.
Commercial crab food is available, but you can also supplement their diet with foods such as shrimp, bloodworms, and boiled vegetables. Make sure to feed your crab once a day, and monitor their health for signs of fungal or bacterial infections, as well as parasites.
Conclusion
Keeping a red claw crab as a pet can be a rewarding experience, provided you do the proper research and provide the necessary care. With the information presented in this article, you’re well on your way to becoming a knowledgeable and responsible red claw crab owner.
Availability and Buying Red Claw Crabs
Red claw crabs are readily available in most pet stores, aquarium shops, and online retailers that sell exotic pets. If you’re interested in purchasing a red claw crab, it’s always best to visit a local fish store first.
In-store, it’s easier to inspect the red claw crabs closely before purchasing them. Look for active and curious crabs, as these are often healthier than those who are hiding or inactive.
It’s also important to check the crabs eyes, claws, and legs to ensure they appear healthy and unharmed. If you don’t have a local fish store, you can always purchase red claw crabs online from a trusted and reputable retailer.
Online stores are often a convenient option for purchasing exotic pets. However, remember that transporting live animals through shipping can be risky, so be sure to check the retailer’s policies and reputation beforehand.
Conclusion and Final Thoughts
Red claw crabs are hardy creatures that can adapt to a variety of environments and conditions. They are easy to care for, resistant to most diseases, and are not prone to any major health issues.
However, it’s still important to research and learn about their specific needs and behaviors before bringing one home. It’s important to note that red claw crabs are not recommended for home breeding.
Unless you are a seasoned breeder with the appropriate equipment and knowledge, breeding red claw crabs at home can be a difficult and sometimes impossible task. Additionally, breeding freshwater crab can lead to overcrowding in the home aquarium and cause territorial disputes.
Before purchasing a red claw crab, make sure to determine the crab’s gender. As mentioned earlier, males typically have larger claws than females, making it an easy way to distinguish gender.
It’s best to purchase multiple females, plus one male to avoid territorial conflicts in the tank. In conclusion, red claw crabs are unique and fascinating creatures that make for great pets.
With their vibrant colors, interesting behaviors, and easy-to-maintain care, they are quickly becoming a favorite among invertebrates lovers. If you’re considering adding a red claw crab to your home aquarium, be sure to do your research and provide them with the necessary care and environment they need to thrive.
