Duncan corals, scientifically known as Duncanopsammia axifuga but often referred to simply as Duncans, are beloved inhabitants of reef aquariums worldwide. With their captivating appearance, gentle swaying tentacles, and relatively easy care requirements, Duncans have become popular choices for both beginner and experienced aquarists. In this blog, we'll explore the beauty and care of Duncan corals, shedding light on why they make an excellent addition to home aquariums.

Discovering the Beauty of Duncan Corals:
Duncan corals are members of the family Dendrophylliidae and are native to the Indo-Pacific region. They are characterized by their distinctive appearance, featuring large polyps adorned with numerous tentacles arranged in a circular pattern. Duncans come in a variety of colors, including shades of green, brown, purple, and even fluorescent hues, adding vibrant splashes of color to reef aquariums. One of the most enchanting features of Duncans is their mesmerizing tentacle movement, which gracefully sways in response to water flow and light intensity, creating a mesmerizing underwater spectacle.

Care Requirements:
Maintaining optimal conditions for Duncan corals is essential for their health and longevity. Here are some key care requirements to consider:

1. Water Parameters: Duncan corals thrive in stable water conditions. Keep temperature between 75-80°F (24-27°C), salinity at 1.024-1.026, pH between 8.1-8.4, and alkalinity (dKH) between 8-10. Regular water testing and adjustments are crucial for maintaining water quality.

2. Lighting: Moderate to low lighting is suitable for Duncan corals, as excessive light can cause tissue damage or bleaching. LED lighting with adjustable intensity and spectrum control allows you to customize the lighting to meet the needs of your corals.

3. Water Flow: Gentle to moderate water flow is ideal for Duncan corals. Position them in areas of the aquarium where water movement is sufficient to promote nutrient exchange and waste removal without causing excessive stress to the coral's delicate tentacles.

4. Feeding: While Duncan corals primarily obtain nutrients through photosynthesis, they can also benefit from supplemental feeding. Offer small, meaty foods such as mysis shrimp, brine shrimp, or specialized coral foods to enhance their growth and coloration.

When placing Duncan corals in your aquarium, consider their placement preferences:

1. Duncans prefer to be placed on the substrate or on elevated rockwork, where they can extend their tentacles freely without obstruction.
2. Provide adequate spacing between Duncan colonies and other corals to prevent territorial disputes and allow for proper water flow around each specimen.
3. Avoid placing Duncans in direct contact with aggressive or stinging corals, as they may engage in territorial behavior.

Duncan corals can be propagated through division, where the coral colony is carefully split into smaller fragments. Using sharp coral cutters, carefully divide the colony into sections, ensuring that each fragment has a portion of the coral's base attached. Attach the fragments to frag plugs or rock surfaces using reef-safe glue or epoxy, and provide optimal water flow and lighting to promote healing and growth in the newly propagated corals.

Duncan corals captivate aquarists with their stunning appearance, gentle movement, and relatively easy care requirements. By providing stable water conditions, appropriate lighting, and careful placement, you can enjoy the beauty of Duncan corals in your own home aquarium. With their vibrant colors and graceful tentacle swaying, Duncans are sure to become cherished inhabitants of your underwater sanctuary, bringing joy and fascination to viewers and enriching the vibrant ecosystem of your aquatic environment.
