Product overview

The Duncan Coral is an exceptionally charming and hardy Large Polyp Stony (LPS) specimen celebrated for its distinctive, dandelion-like polyps that sway gracefully with the current. Featuring lovely green, blue, or muted center discs framed by long, feathery tentacles, this iconic coral introduces wonderful motion, texture, and visual warmth to any marine display.

Care & husbandry guidelines

• To keep your Duncan Coral expanding fully and showing off its best form, provide moderate illumination combined with gentle, indirect water movement that keeps its tissue clean without flattening the polyps.
• While they derive significant energy through photosynthesis via symbiotic zooxanthellae, they are enthusiastic eaters that thrive on regular target feedings of micro-plankton, mysis shrimp, or fine coral foods to accelerate colony branching and color vibrancy.
• Exceptionally peaceful and completely lacking aggressive sweeper tentacles, they make fantastic, stress-free additions for aquarists of all experience levels; simply ensure they have adequate room to branch out and form their magnificent multi-head colonies.

How We Photograph Our Corals

Every WYSIWYG photo on The Twin Corals Shop is captured directly in our systems using meticulous settings to ensure absolute transparency. Our goal is straightforward: show the coral precisely as it appears in a well-maintained reef aquarium — never heavily filtered or artificially saturated.

Our Camera & Optics

• Camera: Panasonic Lumix G85
• Lens / Mode: Olympus M.Zuiko Digital ED 60mm f/2.8 Macro Lens
• ISO: 50
• White Balance: Custom set between 9,000K–10,000K

This setup allows us to highlight the finest structural details — from delicate polyp extension and skeletal texture to subtle gradient color shifts — without washing out the true look of the animal.

Lighting We Shoot Under

• Fixtures: Nicrew Hyperreef Gen2 (100W or 150W depending on the system)
• Photo Spectrum Mix: White 5% · Violet 60% · UV 60% · Deep Blue 50%

Color Accuracy & Your Tank

By utilizing a targeted custom white balance, our photos closely mirror what you will see under a clean, balanced blue-leaning reef spectrum.

Keep in mind that corals are living organisms; their appearance can naturally shift from tank to tank depending on your specific water parameters, nutrient levels, lighting spectrum, and flow patterns. We strive to provide honest, dependable photos you can trust so your new coral looks right at home from day one.
