Acropora loisetteae

• Indo-Pacific
• High Care Level
• For Advanced Hobbyists
• High Placement in Reef Tank

Acropora loisetteae is a stunning branching species of SPS (Small Polyp Stony) coral found in the Indo-Pacific region. Known for its vibrant colors and delicate structure, A. loisetteae is often characterized by its long, slender branches, which can range in colors from pale green to bright blue or purple, depending on the light and water conditions. This species has a unique, open, branching growth form that can add a dynamic and colorful element to a reef aquarium. However, due to its specific care requirements and sensitivity to environmental changes, it is best suited for advanced hobbyists.

Placement in the Tank

Acropora loisetteae thrives under strong lighting, with an intensity of 250-350 PAR being ideal. It should be positioned in the upper sections of the tank, where it can receive intense light, similar to the shallow reef zones where it naturally grows. Additionally, this species requires strong water flow to promote healthy growth and aid in nutrient uptake. High water movement helps keep the coral clean and ensures proper respiration, making it essential for A. loisetteae to be placed where there is consistent water movement.

Water Parameters

For optimal health and growth, maintaining precise water parameters is essential for Acropora loisetteae. The recommended water conditions are:

• Temperature: 24°C to 28°C (75°F to 82°F), with a stable temperature of 26°C (79°F) being ideal.
• Salinity: 1.023–1.025 specific gravity (SG), with 1.024 being optimal.
• pH: 8.0 to 8.4, with an ideal pH of 8.2.
• Alkalinity (dKH): 8-12 dKH, with 9-10 dKH being ideal for stable growth.
• Calcium: 400-450 ppm for optimal skeletal development.
• Magnesium: 1250-1350 ppm.
• Nitrate: Less than 5 ppm, as elevated nitrate levels can stress the coral.
• Phosphate: Below 0.03 ppm to prevent algae overgrowth, which can compete for resources.

Feeding

While Acropora loisetteae relies heavily on zooxanthellae algae for photosynthesis, it can benefit from supplemental feeding to promote growth. Offering zooplankton, phytoplankton, or liquid coral foods will help supplement its diet, especially in aquariums where plankton availability is low. It is important not to overfeed, as this can lead to poor water quality, so feeding should be done sparingly.

Maintenance and Care

Consistent maintenance is essential for ensuring the health and longevity of Acropora loisetteae:

• Water Changes: Perform regular water changes (10-15% weekly) to maintain stable conditions and prevent the buildup of harmful substances.
• Water Parameter Monitoring: Regularly check temperature, pH, alkalinity, calcium, and phosphate to ensure optimal water quality.
• Pruning: Acropora loisetteae may require occasional fragging as it can grow rapidly, especially if left unchecked. Fragging will also help control overcrowding and promote healthier growth.
• Pest Control: Watch for pests such as red bugs, flatworms, and Aiptasia, which can damage the coral. Immediate action should be taken if pests are detected.

Compatibility

Acropora loisetteae is an aggressive species due to its long sweeper tentacles, which can harm nearby corals. It is important to place it away from soft corals and LPS species to prevent stinging or damage. This species does best with other non-aggressive SPS corals that are spaced adequately to avoid competition for resources like light and nutrients.

Conclusion

Acropora loisetteae is a stunning and vibrant addition to a reef aquarium, thanks to its beautiful branching structure and rich color variations. Its high care level makes it best suited for advanced hobbyists who can maintain the precise conditions it needs to thrive. With strong lighting, strong water flow, and consistent water parameters, A. loisetteae can grow well and become a breathtaking centerpiece in your reef tank.
