The Acanthastrea echinata (Ultra) is a large, visually captivating LPS coral from the Mussidae family, known for its bold colours and fleshy polyps. This coral is a prized specimen for marine aquarium enthusiasts looking to add a dramatic focal point to their reef setup.
Care Level: Moderate to advanced. This coral requires stable water parameters and attentive husbandry to thrive.
Lighting Requirements: Moderate lighting is ideal. LED or T5 lighting systems providing a PAR range of 50-150 are recommended to maintain vibrant coloration without causing bleaching.
Water Flow: Moderate, indirect water flow is best. Strong currents can cause tissue damage, while too little flow may lead to detritus accumulation.
Placement: Position the coral on the substrate or lower to middle areas of the rockwork to ensure optimal light exposure and water movement. Provide adequate spacing from neighbouring corals to prevent aggression and tissue damage.
Diet: While photosynthetic, Acanthastrea echinata 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 health.
Reef Compatibility: Yes, with adequate spacing. This coral can coexist with other peaceful LPS and SPS corals but may exhibit aggression if placed too close to other corals.
Origin: Not Provided.
Maximum Size: Large colonies can reach up to 15 cm in diameter under optimal conditions.
Minimum Tank Size: 90 litres (approximately 24 gallons) to provide sufficient space and stable water quality.
Regular monitoring of water parameters such as calcium, alkalinity, magnesium, and nitrates is essential for maintaining coral health. Maintain temperature between 24-26°C and stable salinity around 1.025 specific gravity.
This large Acanthastrea echinata Ultra coral is a premium choice for UK reef keepers seeking a bold and colourful addition to their marine aquarium.
