Acanthastrea echinata (Ultra) is a large polyp stony (LPS) coral known for its bold, fluorescent colours and fleshy polyps. This coral is a popular choice among marine aquarium enthusiasts looking to add vibrant texture and colour to their reef displays.
Lighting Requirements: Moderate lighting is ideal for Acanthastrea echinata. Too intense lighting can cause bleaching, while too little may inhibit growth. LED or T5 lighting systems with adjustable intensity work well.
Water Flow: Moderate, indirect water flow is recommended. Strong currents can damage the delicate polyps, whereas stagnant water may encourage detritus accumulation.
Placement: Position this coral on the substrate or lower to middle sections of the tank where lighting and flow conditions are stable. Ensure adequate spacing from neighbouring corals to prevent aggressive interactions.
Care Level: Intermediate. Requires stable water parameters and regular monitoring to maintain health and vibrant colouration.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from supplemental feeding of meaty foods such as mysis shrimp or specialised coral foods 1-2 times per week.
Reef Compatibility: Yes, with adequate spacing. This coral can coexist with most reef-safe species but may exhibit aggression towards close neighbours.
Origin: Not Provided.
Maximum Size: Colonies can grow up to 15 cm in diameter under optimal conditions.
Minimum Tank Size: Recommended for tanks 75 litres and above to ensure stable water quality and space.
