Crab- Borneo Tricolor
Borneo Tricolor Crabs (Episesarma mederi), also known as Borneo Rainbow Crabs, are attractive and colorful crustaceans that require specific care to thrive in captivity. Here are their care requirements:
Habitat Requirements
Tank Setup: A paludarium or aquarium with both land and water areas is ideal. A 10-gallon tank is the minimum size for a small group of 2-3 crabs.
Substrate: Use a mix of sand and gravel to create both aquatic and terrestrial areas. Sand is particularly important for burrowing.
Hiding Places: Provide plenty of hiding spots with rocks, driftwood, and plants to mimic their natural habitat and reduce stress.
Plants: Include live or artificial plants for cover and climbing opportunities. Hardy plants like Java fern or Anubias can tolerate brackish conditions.
Water Parameters
Brackish Water: Borneo Tricolor Crabs require slightly brackish water with a specific gravity of 1.005-1.010. Use marine salt to achieve this.
Temperature: Keep the water temperature between 75-82°F (24-28°C).
pH: Maintain a pH level between 7.5 and 8.5.
Hardness: Water hardness should be between 8-12 dGH.
Filtration: Use a gentle filter to maintain water quality and provide good water circulation without creating strong currents. Sponge filters are a good option.
Water Changes: Perform regular water changes (20-30% weekly) to maintain water quality.
Land Area
Dry Land: Ensure the tank has a secure land area where the crabs can climb out of the water completely. This can be achieved with rocks, floating platforms, or sloped substrate.
Humidity: Maintain moderate humidity levels in the land area by misting it regularly.
Feeding
Omnivorous Diet: Borneo Tricolor Crabs are omnivorous and need a varied diet.
Natural Diet: In the wild, they eat algae, detritus, small invertebrates, and plant matter.
Feeding in Captivity: Offer a variety of foods including commercial crab pellets, fish flakes, freeze-dried or frozen bloodworms, brine shrimp, and vegetables (e.g., spinach, peas, zucchini). You can also provide occasional protein sources like small pieces of fish or shrimp.
Frequency: Feed them once a day, removing any uneaten food to prevent water quality issues.
Behavior and Compatibility
Territorial Nature: Borneo Tricolor Crabs can be territorial, especially males. Provide ample space and hiding spots to reduce aggression.
Social Behavior: They are best kept in groups with a larger ratio of females to males (e.g., 1 male to 2-3 females) to minimize territorial disputes.
Tank Mates: They are best kept with other semi-aquatic crabs or small, fast-moving fish that can tolerate brackish water. Avoid slow-moving or bottom-dwelling fish, as they may be harassed or eaten.
Maintenance
Cleaning: Regularly clean and spot-clean the tank to remove waste and uneaten food.
Substrate Maintenance: Stir the substrate occasionally to prevent anaerobic pockets and maintain cleanliness.
Monitoring: Observe their behavior and health regularly. Look out for signs of stress, illness, or molting issues.
Molting
Molting Process: Borneo Tricolor Crabs molt as they grow. During this time, they are vulnerable and will hide. Ensure they have plenty of hiding spots and leave their old exoskeleton in the tank for them to consume, as it provides essential nutrients.
Calcium: Provide a calcium source (e.g., cuttlebone or crushed coral) to support healthy shell development.
Additional Considerations
Escape Prevention: Ensure the tank has a tight-fitting lid, as Borneo Tricolor Crabs are excellent climbers and may escape.
Handling: Minimize handling, as it can stress the crabs and they may pinch.
Breeding: Breeding Borneo Tricolor Crabs in captivity is challenging and not commonly achieved due to their specific habitat and breeding requirements.
By providing a suitable paludarium setup with appropriate water conditions, land areas, and a varied diet, Borneo Tricolor Crabs can thrive and display their unique and captivating behaviors in captivity.
