Rainbow Acan – A Dazzling Burst of Color for Your Reef

The Rainbow Acan (Acanthastrea lordhowensis) is a stunning LPS coral prized for its vibrant mix of reds, oranges, purples, blues, and greens, creating a mesmerizing kaleidoscope of colors. With its fleshy polyps and unique boulder-like growth pattern, this coral is a perfect addition to both beginner and expert reef tanks, adding intense color and texture to your aquascape.

Care Instructions:

• Lighting: Low to moderate (PAR 50-150) – Too much light may cause bleaching or retraction
• Flow: Low to moderate – Gentle flow is best to allow full polyp extension
• Placement: Low to mid-level on rockwork or sandbed for optimal growth and color
• Water Parameters:
  • Temperature: 76-80°F
  • Salinity: 1.024-1.026 SG
  • pH: 8.1-8.4
  • Alkalinity: 8-10 dKH
  • Calcium: 400-450 ppm
  • Magnesium: 1300-1400 ppm
  • Nitrate: 5-15 ppm
  • Phosphate: 0.03-0.10 ppm

Feeding & Growth:

The Rainbow Acan is highly responsive to feeding and will benefit from regular target feeding with meaty foods like mysis shrimp, brine shrimp, or LPS-specific coral foods. Feeding encourages brighter coloration, faster polyp growth, and increased tissue expansion.

Compatibility & Special Considerations:

• Moderately aggressive – Can extend feeder tentacles at night, so allow some space from neighboring corals
• Can be fragged easily to propagate and share
• Best color development occurs with moderate lighting and regular feedings
