Acanthastrea lordhowensis (Ultra) is a stunning large polyp stony (LPS) coral from the Mussidae family, renowned for its vibrant colours and unique patterns. This small-sized specimen is perfect for hobbyists looking to enhance their reef tank with a visually striking coral.
Care Level: Moderate care is recommended. This coral thrives under stable water conditions and requires consistent maintenance to flourish.
Lighting Requirements: Moderate lighting is ideal. LED or T5 lighting systems that provide a balanced spectrum will support healthy growth and vibrant coloration.
Water Flow: Low to moderate water flow is preferred to ensure the coral’s delicate polyps are not damaged while maintaining adequate nutrient exchange.
Placement: Position this coral on the substrate or lower to middle sections of the rockwork. Ensure adequate spacing from neighbouring corals to prevent aggressive interactions, as Acanthastrea can extend sweeper tentacles.
Diet: While photosynthetic, Acanthastrea lordhowensis benefits from supplemental feeding. Offer meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods 1-2 times per week to promote growth and vibrancy.
Reef Compatibility: Yes, with adequate spacing. This coral is generally reef safe but can be aggressive towards nearby corals due to its sweeper tentacles.
Origin: Not Provided.
Maximum Size: Typically grows up to 15 cm in diameter under optimal conditions.
Minimum Tank Size: A minimum of 75 litres (20 gallons) is recommended to provide stable water parameters and sufficient space.
Regular water testing and stable parameters are essential for maintaining the health of Acanthastrea lordhowensis. Maintain temperature between 24-27°C, salinity at 1.023-1.025 SG, and stable alkalinity and calcium levels.
