💙🌟 Blue Nebula Long-Coralite Tenuis
Acropora tenuis – Extended Coralites & Mega Polyp Structure (WYSIWYG)
Please note: This is a WYSIWYG listing — you will receive the exact colony shown.
🔹 Quick Stats
Care Level: Advanced
Temperament: Peaceful
Colour Form: A striking long-coralite Acropora tenuis displaying deep, ocean-blue branches wrapped in oversized, high-definition polyps. Each elongated coralite forms a sculpted, architectural pattern, while the mega polyps extend in a bright frosted-blue glow under actinic spectrum. In daylight, the colony shows rich sapphire tones; under blue LED, it shifts into an ethereal ice-blue radiance with dramatic texture.
Water Conditions: 24–26 °C, dKH 8–9, pH 8.1–8.4, sg 1.024–1.026
Family: Acroporidae
Lighting: High (PAR 300–400 for full saturation)
Water Flow: Strong, alternating
Placement: Upper rockwork
🧬 Overview
The Blue Nebula Long-Coralite Tenuis is a standout specimen for SPS collectors who appreciate both structure and colour. Its extended coralites give it a unique, jagged silhouette, while the mega polyp coverage creates a plush, textured appearance rarely seen in tenuis morphs.
Under high-energy reef lighting, the coral reveals layered shades of sapphire, glacier-blue, and metallic frost — a dynamic palette that shifts throughout the day. Its bold architecture and dramatic polyp extension make it an exceptional centrepiece for modern SPS aquascapes.
🍽️ Care & Feeding
Fully photosynthetic, but colour density and polyp health improve with occasional fine coral foods (Reef Roids, Coral Dust, or Phytoplankton). Maintain stable alkalinity and strong trace-element balance (iron, potassium, manganese) to sustain its blue fluorescence and polyp extension.
📈 Optimal Parameters
| Parameter | Ideal Range |
|---|---|
| Alkalinity (dKH) | 8–9 |
| Calcium (Ca) | 430–460 ppm |
| Magnesium (Mg) | 1300–1400 ppm |
| Nitrate (NO₃) | 2–10 ppm |
| Phosphate (PO₄) | 0.02–0.08 ppm |
📍 Placement
Position high on the reef structure with strong, turbulent flow and direct lighting to maximise its blue saturation and maintain long-coralite definition. Avoid shading to preserve the polyp glow from base to tip.
💙🌟 Blue Nebula Long-Coralite Tenuis
A rare structural masterpiece — where sapphire tone meets mega-polyp brilliance, creating a luminous, textural showpiece for the true SPS connoisseur.
