The Green‑Stem Duncan Coral is a hardy, fast‑growing LPS coral known for its long, flowing tentacles, bright green stalks, and gentle movement. It’s one of the most beginner‑friendly LPS species, but it’s also colorful and expressive enough to be a staple in advanced mixed reefs. 🌿 Identity & Appearance Green‑stem Duncans (Duncanopsammia axifuga) are instantly recognizable because of their glowing stalks and soft, anemone‑like polyp extension. Typical traits include: • Bright neon‑green stems (the signature feature) • Long, flowing tentacles in shades of tan, purple, or green • Round, daisy‑like oral disc • Branching skeleton that forms new heads over time • Soft, rhythmic movement in gentle flow Under blue LEDs, the green stems and oral discs fluoresce intensely. 🌱 Growth & Behavior Duncans are fast growers once settled. You’ll see: • New heads budding from the base and sides • Polyps expanding widely during the day • Strong feeding response • Colonies forming large, branching clusters They’re expressive corals—open and full when happy, slightly withdrawn when irritated. 💡 Lighting Requirements Green‑stem Duncans prefer moderate light. • PAR 80–150 is ideal • Too much light can cause retraction • Too little light slows growth They’re flexible and adapt well to a variety of lighting setups. 🌊 Flow Preferences Flow should be low to moderate and indirect. • Gentle sway keeps tentacles moving naturally • Avoid direct jets that cause the polyps to stay closed • Stable, rhythmic flow helps maintain full extension They enjoy the same flow zones as hammers and frogspawn. 🍤 Feeding & Nutrition Duncans love to eat, and feeding dramatically boosts growth. They accept: • Mysis • Brine • Reef plankton • LPS pellets • Small meaty blends Feeding 1–2× weekly encourages rapid head formation and fuller polyps. 🧪 Water Parameters & Hardiness Duncans are very hardy, making them excellent for beginners and stable mixed reefs. They prefer: • NO₃ 5–15 ppm • PO₄ 0.03–0.1 ppm • Alk 8–9 dKH • Stable salinity and temperature They tolerate minor swings better than many LPS but still thrive with consistency. ⚔️ Aggression & Spacing Duncans are peaceful and safe to place near most corals. • No long sweepers • Minimal stinging ability • Give 1–2 inches of space for comfort They’re great neighbors in mixed LPS gardens. ⭐ Why Reefers Love It • Bright, glowing green stems that stand out under blues • Soft, flowing movement • Fast growth and easy care • Peaceful and versatile placement • Great for beginners and advanced tanks alike
