🔴🔥✨ Acropora sp. “Crimson Fury” (Indonesia Red)
SPS Coral – Deep Blood-Red Branching Acropora with Extreme Saturation (Cut to Order Frag)
🔹 Quick Stats
Care Level: Advanced
Temperament: Peaceful
Colour Form: The “Crimson Fury” displays an intense, true blood-red base across the branches, with darker wine-red shadows in the corallites and brighter scarlet highlights on the growth points. Under actinic lighting, the red deepens into glowing ruby tones with subtle ember fluorescence. Under white light, the coral shows rich cherry-red to crimson hues with zero brown washout — clean, aggressive and unmistakably red.
Water Conditions: 24–26 °C, dKH 7.5–9, pH 8.0–8.4, sg 1.024–1.026
Family: Acroporidae
Lighting: High (PAR 250–350)
Water Flow: Strong, random and turbulent
Placement: Upper rockwork / high-energy zones
🧬 Overview
The Acropora “Crimson Fury” (Indonesia Red) is a true red-spectrum SPS, not pink, not rust, not orange — proper blood red. These morphs are notoriously hard to keep saturated, which makes stable red acros extremely sought after by advanced collectors.
Branching is strong and structured, with pronounced axial tips and tight corallite spacing. Under high light and strong flow, the red intensifies and the growth tips glow like hot coals, giving a constant ember effect.
This piece is offered cut to order, freshly fragged from a mature, colour-stable Indonesian mother colony with proven long-term performance.
Each cut-to-order frag is selected for:
• True deep red saturation (not brown, not pink)
• Strong axial growth points
• Clean tissue with no fading zones
• Healthy, pest-free structure
• Proven colour stability under high-end LED systems
• Fast encrusting base and aggressive growth pattern
An SPS reserved for reefers who want real red in their acro garden.
🍽️ Care & Feeding
Red acros perform best in stable, nutrient-present systems.
Feed 2–3× weekly with:
• Amino acids (especially colour-enhancing blends)
• Phytoplankton & zooplankton
• Fine coral foods (reef roids, powders)
• Maintain detectable NO₃/PO₄ to avoid colour washout
📈 Optimal Parameters
| Parameter | Ideal Range |
|---|---|
| Alkalinity (dKH) | 7.5–9 |
| Calcium (Ca) | 420–450 ppm |
| Magnesium (Mg) | 1300–1400 ppm |
| Nitrate (NO₃) | 2–10 ppm |
| Phosphate (PO₄) | 0.03–0.08 ppm |
📍 Placement
Place in upper rockwork with strong, chaotic flow.
Ensure high light exposure to maintain red saturation.
Avoid shaded zones or low-flow pockets — red morphs fade fast without energy.
