Green Acan Lord (Acanthastrea lordhowensis) – Care Guide
Green Acan Lords are a vibrant addition to any LPS collection, with fleshy polyps and glowing green centers that shimmer under actinic lighting. Their puffed-up texture and slow pulsing movement make them both a visual and textural showpiece.
Care Level: Easy
Lighting: Low to Moderate (50–150 PAR)
Flow: Low to Moderate – enough to keep detritus off but gentle on tissue
Placement: Sandbed or lower rockwork – give room to expand and avoid stings from sweepers
Water Parameters:
• Temp: 76–78°F
• Salinity: 1.025
• dKH: 8–10
• Calcium: 400–450 ppm
• Magnesium: 1300–1400 ppm
• Nitrate: 2–10 ppm
• Phosphate: 0.01–0.1 ppm
Feeding:
While photosynthetic, they benefit from occasional target feeding with meaty foods like mysis, brine, or reef-roids—especially at night when feeder tentacles are extended.
Growth Tips:
Keep water parameters stable and avoid aggressive neighbors. Green Acans grow well when fed and will expand outward in domed colonies.
📦 Note: Frags are not WYSIWYG – color intensity and pattern vary slightly per polyp.
