🧬 Overview
The Acropora cerealis “Emerald Crown” is a visually striking SPS coral prized for its vibrant green base coloration and dramatic purple growth tips. Acropora cerealis typically develops compact branching colonies with pronounced coralites and strong axial tips, giving the coral a bold and structured appearance.
The emerald-green tissue provides intense fluorescence under reef LED lighting, while the purple tips form a crown-like highlight at the ends of each branch. This natural contrast creates a beautiful and eye-catching effect, especially when placed near other SPS corals with warm or blue colour tones.
As the colony matures, the branching structure becomes denser and more intricate, forming a vibrant coral cluster that adds colour and depth to SPS-dominated reef aquascapes.
WYSIWYG:
You will receive the exact coral shown in the photo. Each specimen is individually photographed and selected for colour saturation, structure and coral health.
Selected for:
• Vibrant emerald-green base coloration
• Distinct purple growth tips
• Healthy tissue and visible growth tips
• Strong fluorescence under reef LED lighting
• Beautiful natural colour contrast for SPS reefs
🍽️ Care & Feeding
Like most Acropora species, Emerald Crown relies mainly on photosynthesis but benefits from stable nutrient levels and occasional coral feeding.
Recommended feeding 1–2× weekly:
• Fine plankton blends or powdered coral foods
• Amino acid supplements for SPS systems
• Broadcast feeding in mature reef aquariums
📈 Optimal Parameters
Parameter | Ideal Range
Alkalinity (dKH) | 7.5–8.5
Calcium (Ca) | 420–450 ppm
Magnesium (Mg) | 1300–1400 ppm
Nitrate (NO₃) | 5–15 ppm
Phosphate (PO₄) | 0.03–0.10 ppm
📍 Placement
Place in the upper aquascape where strong lighting and turbulent water flow are present. Acropora cerealis thrives in high-energy reef zones where strong flow promotes healthy growth and vibrant coloration.
Allow sufficient spacing between neighbouring SPS colonies to support natural branch development.
