Acanthastrea lordhowensis, commonly known as Lord Howe Acan, is a popular large polyp stony (LPS) coral prized for its vivid colours and robust growth. This premium large specimen is ideal for marine aquarists looking to add a bold and textured coral to their reef display.
Lighting: Moderate lighting is recommended, such as LED or T5 fixtures providing PAR levels between 50-150. Avoid intense direct light to prevent bleaching.
Water Flow: Moderate, indirect water flow is ideal to ensure healthy polyp extension without causing tissue damage.
Placement: Position on the substrate or lower to mid-level rockwork with adequate space to prevent aggression. This coral can extend sweeper tentacles, so maintain at least 5-7 cm distance from neighbouring corals.
Care Level: Suitable for intermediate to advanced hobbyists due to moderate care requirements and sensitivity to water quality fluctuations.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from supplemental feeding of meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods 1-2 times weekly.
Reef Compatibility: Yes, with adequate spacing to avoid aggression.
Origin: Native to the Indo-Pacific region, including Lord Howe Island.
Maximum Size: Colonies can grow up to 30 cm or more under optimal conditions.
Maintain stable water parameters with temperature 24-27°C, salinity 1.023-1.025, pH 8.1-8.4, and low nutrient levels to ensure vibrant health and growth.
