💛⚡ Ultra Yellow Hammer Coral (Ancora)
Euphyllia ancora – Fluorescent Gold LPS Colony
🔹 Quick Stats
Care Level: Intermediate
Temperament: Aggressive (keep distance from other corals)
Colour Form: A breathtaking fluorescent yellow Euphyllia ancora displaying long, curved hammer-shaped tentacles glowing in shades of pure gold and neon lemon. Under actinic or blue lighting, the colony radiates a molten effect — a field of living sunlight that sways gracefully in the current. Its uniform yellow tone and smooth, flowing motion make it one of the rarest and most captivating hammer corals available.
Water Conditions: 24–27 °C, dKH 8–11, pH 8.0–8.4, sg 1.024–1.026
Family: Euphylliidae
Lighting: Moderate to High – enhances golden and yellow fluorescence
Water Flow: Moderate, oscillating
Placement: Mid to lower reef zones with room for expansion
🧬 Overview
The Ultra Yellow Hammer Coral (Ancora) is a collector-grade LPS revered for its brilliant colour saturation and gentle rhythmic movement. Each colony forms dense walls of fleshy polyps that undulate with hypnotic grace, capturing and reflecting light like liquid gold.
This morph’s intense yellow pigmentation remains stable under proper lighting and nutrient balance, offering a radiant centrepiece for both mixed and LPS-dominated aquascapes. Its balance of elegance and intensity makes it a must-have coral for serious collectors.
🍽️ Care & Feeding
Fully photosynthetic, but benefits from target feeding once or twice per week with Reef Roids, Coral Frenzy, or fine Mysis shrimp to promote growth and polyp fullness.
Maintain stable alkalinity and trace elements (especially Iron, Potassium, and Manganese) to preserve vibrant yellow tones.
Avoid strong, direct flow — moderate oscillation keeps the tissue gently in motion without tearing.
📈 Optimal Parameters
| Parameter | Ideal Range |
|---|---|
| Alkalinity (dKH) | 8–11 |
| Calcium (Ca) | 420–460 ppm |
| Magnesium (Mg) | 1250–1350 ppm |
| Nitrate (NO₃) | 2–10 ppm |
| Phosphate (PO₄) | 0.02–0.07 ppm |
📍 Placement
Place in moderate, indirect flow and medium lighting zones to allow the colony’s polyps to expand fully and sway naturally. Keep 10 cm or more of space from neighbouring corals — Euphyllia ancora can extend long sweeper tentacles at night.
Ideal for creating visual contrast against darker or blue-toned LPS colonies.
