Green Duncans (Duncanopsammia axifuga)

Hardy, Flowing LPS Coral 💚🪸

Green Duncans, scientifically known as Duncanopsammia axifuga, are one of the most popular and beginner-friendly large polyp stony (LPS) corals in the reef hobby. Loved for their bright green tentacles, contrasting centres, and constant gentle movement, Green Duncans bring colour, life, and personality to reef aquariums of all sizes.

This coral is highly regarded for its resilience and adaptability, making it an excellent choice for both new reef keepers and experienced hobbyists. Under proper care, Green Duncans display excellent polyp extension throughout the day, creating a soft, flowing effect that enhances the natural look of your reef. Their peaceful nature and tolerance of a wide range of conditions make them an easy addition to mixed reef systems.

Care & Placement 🧪

Lighting:
Low to moderate lighting is ideal. Green Duncans adapt well to LED and T5 systems and can tolerate slightly higher light once acclimated.

Water Flow:
Low to moderate, indirect flow is best. Flow should allow the tentacles to sway gently without being forced closed.

Placement:
Suitable for placement on the sandbed or lower to mid rockwork. Ensure stable positioning to allow for growth and easy feeding.

Water Parameters:

• Temperature: 24–26°C

• Salinity: 1.024–1.026

• Alkalinity: 8–9 dKH

• Calcium: 400–450 ppm

• Magnesium: 1250–1350 ppm

Maintaining stable parameters encourages consistent polyp extension and healthy skeletal growth.

Feeding & Growth 🍽️📈

While Green Duncans rely on photosynthesis, they benefit greatly from regular target feeding. Foods such as mysis shrimp, chopped seafood, reef pellets, or coral blends help accelerate growth and encourage larger, fuller polyps.

Green Duncans are known for their fast growth rate when fed regularly. New heads form from the base of the skeleton, creating attractive branching colonies over time.

Reef Compatibility 🐠

• ✔ Reef safe

• ✔ Peaceful temperament

• ✔ Suitable for mixed reefs

Green Duncans do not have aggressive sweeper tentacles and generally coexist well with other corals, making them an excellent choice for community reef tanks. Standard spacing is sufficient.

Aquascaping Inspiration 🪨

Green Duncans work beautifully as colony-forming corals, filling space with movement and colour without overwhelming the aquascape. They look especially striking when grouped in small clusters or used as a mid-ground feature in mixed reef setups alongside soft corals and SPS.
