Duncan Coral Care Guide – Flow, Glow, and Easy Growth
Duncan corals are hardy, fast-growing LPS corals with elegant, tentacle-like polyps and a glowing green or purple center. They’re perfect for both beginners and experienced reefers looking to add motion and structure to their tank.
Care Highlights:
💡 Lighting: Low to moderate PAR (80–150) – thrives under LED, T5, or hybrid setups
🌊 Flow: Moderate, indirect – enough to keep polyps gently moving without blasting the tissue
📍 Placement: Lower to mid tank; can be mounted on rock or sandbed with room to grow outward
🍽️ Feeding: Benefits from 1–2x/week target feeding (mysis, reef roids, or amino acids)
🧪 Parameters:
Temp: 75–78°F
Salinity: 1.025
dKH: 8–11
Calcium: 420–460 ppm
Magnesium: 1300+ ppm
Nitrates: 2–10 ppm
Phosphates: 0.02–0.08 ppm
Pro Tips:
Grows heads quickly with feeding and stable parameters
Peaceful – plays well with most other corals
Polyps extend fully during the day and retract at night
Care Level: Easy – Ideal for beginners and great for mixed reef setups
📦 Note: Frags are not WYSIWYG, but will be healthy, aquacultured pieces with similar color and structure.
