Duncan (single Head)
Duncan corals, scientifically known as Duncanopsammia axifuga, are a popular and visually striking species of stony coral. They are often referred to by different common names such as whisker coral, Duncan coral, or duncanops coral. Here's some information on the care of Duncan corals:
Water Parameters:
Temperature: Duncan corals thrive in temperatures ranging from 74°F to 82°F (23°C to 28°C).
Salinity: Maintain a stable salinity level between 1.023 and 1.025 specific gravity.
pH: Aim for a pH level of around 8.1 to 8.4.
Alkalinity and Calcium: Ensure appropriate levels of alkalinity (8-12 dKH) and calcium (380-450 ppm) to support coral growth and skeletal development.
Nitrate and Phosphate: Keep nitrate levels below 10 ppm and phosphate levels below 0.05 ppm to prevent excessive algae growth and promote coral health.
Lighting:
Duncan corals can adapt to a range of lighting intensities. They can thrive under moderate to high lighting conditions.
Provide them with a suitable spectrum of light, such as a combination of blue and white LEDs or T5 fluorescent bulbs.
Water Flow:
Moderate water flow is generally suitable for Duncan corals. It helps remove waste, provides oxygenation, and prevents debris from settling on the coral.
Ensure there is enough flow to keep the coral clean, but avoid placing it in an area with excessively strong or turbulent flow, which may cause the polyps to retract.
Feeding:
Duncan corals are primarily photosynthetic and obtain the majority of their nutrition from symbiotic zooxanthellae. Adequate lighting is crucial for the zooxanthellae to thrive.
While they can capture some small food particles from the water column, Duncan corals have relatively low feeding requirements compared to some other corals.
However, supplemental feeding with coral-specific planktonic foods can be beneficial, especially for enhancing their coloration and promoting faster growth. You can occasionally target feed them using a turkey baster or a pipette.
Placement:
Duncan corals should be placed in an area with appropriate lighting and water flow.
They appreciate some space around them to allow for the extension of their long, delicate tentacles without interfering with neighboring corals.
Regular Maintenance:
Regularly monitor water parameters using reliable test kits and maintain stable conditions.
Perform routine water changes to replenish trace elements and maintain water quality.
Keep an eye out for any signs of stress, such as polyp retraction, pale coloration, or tissue recession, and take appropriate action if needed.
Duncan corals are generally considered hardy and adaptable, making them suitable for reef aquariums. However, individual corals may have varying sensitivities and preferences, so it's important to observe their response and make adjustments accordingly. Providing stable and optimal water conditions will help promote the health and vibrancy of Duncan corals in your aquarium.
