Green Hammer Coral

Bright Color & Beautiful Motion for Your Reef

The Green Hammer Coral (Euphyllia ancora / Euphyllia paraancora) is a true showpiece in any reef aquarium, loved for its vibrant green hammer-shaped tentacles and mesmerizing, flowing movement. Its luminous coloration ranges from soft lime to intense neon green, glowing beautifully under actinic or blue reef lighting. This coral instantly transforms your aquascape with both color and motion, making it a favourite centerpiece coral among hobbyists.

Hardy and relatively easy to care for, the Green Hammer Coral adapts well to a wide range of reef conditions, thriving in moderate lighting and gentle to moderate water flow. Whether placed as a single head frag or grown into a large colony, it brings a captivating natural elegance to both mixed and LPS-only reef tanks.

💚 Why You’ll Love It

• 💡 Vivid Green Coloration – Radiant fluorescent green tones that pop under blue or actinic lights.

• 🌊 Graceful Movement – Swaying hammer-shaped tentacles add dynamic motion to your reefscape.

• 🪸 Great Centerpiece Coral – Ideal focal coral for both small and large aquariums.

• 🐠 Reef-Safe Beauty – Compatible with most reef-safe fish and peaceful tankmates.

• 🌿 Hardy & Adaptable – Perfect balance of beauty and resilience for beginner to advanced reefers.

🧼 Care & Placement

• Lighting: Moderate lighting levels help maintain vibrant color without stressing the tissue. LEDs or T5s with actinic spectrum work best.

• Flow: Gentle to moderate, indirect water flow allows the polyps to sway naturally without tearing.

• Water Parameters: Temperature 24–27°C, salinity 1.025, calcium 400–450 ppm, alkalinity 8–12 dKH, magnesium 1250–1350 ppm. Stable conditions are essential for long-term success.

• Placement: Mid to lower levels of the aquarium, with adequate space between neighboring corals. The tentacles can extend well beyond the skeleton and may sting nearby species.

• Feeding: While primarily photosynthetic, occasional target feeding with small meaty foods or coral nutrition blends promotes faster growth and stronger polyp extension.

🪴 Aquascaping Inspiration

The Green Hammer Coral is perfect for aquascapers seeking both motion and contrast. Place it where water flow creates gentle waves to highlight its rhythmic movement. It pairs beautifully with Torch, Frogspawn, and Candy Cane corals for a colorful Euphyllia garden, or use it as a vivid accent among soft corals and zoanthids.

Group several heads together for a lush, dome-shaped colony or feature a single frag as a glowing centerpiece. Its radiant hue provides a stunning color contrast against purples, blues, and oranges within your reef.

⚠️ Warning

Like all Euphyllia species, the Green Hammer Coral has sweeper tentacles that can extend and sting nearby corals. Provide at least 5–10 cm of space between it and other species. Avoid contact with delicate SPS or soft corals. Always handle gently to prevent tissue damage when placing or fragging.
