❤️💚 Hyacinthus Red & Green Acropora
Acropora hyacinthus – Bicolour Table Coral Masterpiece
🔹 Quick Stats
Care Level: Advanced
Temperament: Peaceful
Colour Form: A breathtaking fusion of emerald green plates and crimson to cherry-red growth tips, forming a vivid bicolour contrast across its table-like structure. Under actinic lighting, the coral glows with surreal intensity — the red pigments ignite with fire while the green fluoresces like jade crystal.
Water Conditions: 24–27 °C, dKH 8–11, pH 8.0–8.4, sg 1.024–1.026
Family: Acroporidae
Lighting: High (essential for maintaining vivid pigmentation)
Water Flow: Strong, broad and non-laminar
Placement: Upper reef zones with open horizontal space
🧬 Overview
The Hyacinthus Red & Green Acropora is a collector’s showpiece known for its table-forming architecture and stunning dual-tone pigmentation. Its broad, plate-like branches expand outward to form a natural canopy of colour — glowing green base tissue overlain with rich red growth edges.
One of the most visually dramatic Acropora species in the hobby, this coral adds both structure and intense colour balance to any SPS reef. When viewed from above, the coral displays an almost floral geometry, with hues that shift fluidly between ruby and lime under different lighting angles.
🍽️ Care & Feeding
Fully photosynthetic, but thrives when supplemented with amino acids and occasional particulate coral food (e.g. Reef Roids, Coral Vitaliser).
Requires strong turbulent flow to prevent debris buildup on the wide plating surface. Stability in alkalinity and trace elements (especially iron and potassium) enhances both red and green pigment expression.
📈 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) | 0.01–0.05 ppm |
📍 Placement
Position in high-light zones with wide open space for horizontal growth. Avoid shading beneath the plates, and provide sufficient flow across all areas of the coral to keep tissue clean and polyp extension active.
