🧬 Overview
The Acanthastrea lordhowensis “Rainbow Nebula” is a highly sought-after Australian LPS coral known for its vivid multi-colour pattern and thick fleshy polyps. Rainbow Acan Lords are prized by collectors because each polyp can display several colours at once, creating a beautiful mosaic-like effect across the colony.
Under modern reef LED lighting the coral’s fluorescent pigments become especially intense, with bright greens, fiery oranges and deep reds glowing across the coral tissue.
As the colony grows, additional polyps form around the base, gradually developing into a dense and colourful Acan cluster that adds movement and vibrant colour to reef aquascapes.
WYSIWYG:
You will receive the exact coral shown in the photo. Each specimen is individually photographed and selected for colour intensity, polyp structure and coral health.
Selected for:
• Strong rainbow multi-colour pattern
• Thick fleshy Australian Acan polyps
• Excellent fluorescence under reef LED lighting
• Vibrant colour contrast in reef aquascapes
• Great colony growth potential
🍽️ Care & Feeding
Acanthastrea corals benefit from regular feeding and nutrient-balanced reef environments.
Recommended feeding 1–2× weekly:
• Mysis shrimp
• Finely chopped seafood
• LPS pellets or coral foods
• Target feeding during evening polyp expansion
📈 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 on the lower rockwork or sand bed where lighting is moderate and water flow is gentle. Provide enough space around the coral as Acan Lords can extend short feeding tentacles during feeding periods.
Avoid placing the coral too close to aggressive LPS species.
