Acanthastrea echinata (Ultra) is a stunning large polyp stony (LPS) coral prized for its vivid colours and unique texture. This tiny-sized, tank-bred specimen is ideal for hobbyists seeking to enhance their reef aquariums with a hardy and visually captivating coral.
Lighting Requirements: Moderate lighting is recommended to maintain vibrant colours without causing stress. LED or T5 lighting systems providing a PAR range of 50-150 are suitable.
Water Flow: Moderate, indirect water flow is ideal to ensure the coral’s polyps can extend fully without being damaged by strong currents.
Placement: Position this coral on the substrate or lower to middle areas of the tank where it can receive moderate light and flow. Ensure adequate spacing from neighbouring corals to prevent aggression and stinging.
Care Level: Suitable for intermediate aquarists with some experience in LPS coral husbandry. Regular water quality monitoring and stable parameters are essential.
Diet: While Acanthastrea echinata benefits from photosynthesis via its symbiotic zooxanthellae, supplemental feeding with meaty foods such as mysis shrimp or specialised coral foods 1-2 times per week will promote growth and colour intensity.
Reef Compatibility: Yes, with adequate spacing. This coral can coexist peacefully with other reef inhabitants if given enough room to expand.
Origin: Not Provided
Maximum Size: Typically grows to approximately 10 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.
