SULAWESI RED ORCHID

Red Orchid Sulawesi Shrimp (Caridina cf. babaulti), also known for its vibrant red color and unique patterns, is a striking and relatively rare species of freshwater shrimp native to the Sulawesi region of Indonesia. Here’s a detailed guide to ensuring their health and well-being in an aquarium:

Tank Size and Setup

• Tank Size: A minimum of 10 gallons is recommended for a small group of Red Orchid Sulawesi Shrimp. Larger tanks (20 gallons or more) provide better stability in water conditions and more space for these active shrimp.
• Aquascape: Create an environment that mimics their natural habitat with rocks, driftwood, and caves. These structures provide hiding spots and areas for exploration. Smooth lava rocks and ceramic decorations are ideal. Aim for a combination of open space and covered areas to help reduce stress.
• Substrate: Use a dark, fine-grained substrate such as sand or fine gravel. Avoid substrates with sharp or rough edges that could injure the shrimp.
• Plants: While not essential, hardy, low-light plants like Java fern, Anubias, or moss can enhance the tank’s appearance and provide additional surfaces for biofilm growth. Floating plants can also provide shaded areas.

Water Parameters

• Temperature: Maintain a warm water temperature between 78-86°F (25-30°C). Use a reliable aquarium heater to ensure consistent temperatures.
• pH: Red Orchid Sulawesi Shrimp require alkaline water with a pH range of 7.8 to 8.4. Consistent pH levels are crucial for their health.
• Hardness: They thrive in hard water with a general hardness (GH) of 6-8 dGH and a carbonate hardness (KH) of 4-6 dKH. Adequate mineral content is essential for their exoskeleton and overall health.
• Water Quality: These shrimp are sensitive to poor water quality. Perform regular water changes of 10-20% weekly to maintain good conditions. Use dechlorinated water that matches the tank’s temperature and parameters. Adding specialized shrimp mineral supplements or liquid rock salt can help maintain appropriate hardness and mineral levels.

Filtration and Water Flow

• Filtration: Use a sponge filter or a gentle hang-on-back filter that provides effective filtration without creating strong currents. Sponge filters are particularly beneficial as they offer additional surface area for biofilm growth, which the shrimp feed on.
• Water Flow: Red Orchid Sulawesi Shrimp prefer gentle water flow. Avoid strong currents that could stress them. Use tank decorations to help diffuse water flow if needed.

Feeding

• Diet: In the wild, Red Orchid Sulawesi Shrimp feed on biofilm, algae, and microorganisms. In captivity, provide high-quality shrimp pellets or wafers, and supplement with blanched vegetables like spinach or zucchini. They also benefit from occasional live or frozen foods such as baby brine shrimp, daphnia, or powdered spirulina.
• Feeding Frequency: Feed small amounts 2-3 times a week. Ensure food is consumed within a few hours to prevent water quality issues. Remove any uneaten food to avoid decay.
