Caulastrea echinulata is a visually captivating large polyp stony (LPS) coral from the Faviidae family, prized for its vibrant colours and distinctive polyp structure. This extra large specimen offers a bold focal point for mature reef tanks.
Lighting: Moderate to high lighting is recommended to maintain optimal colouration and health. LED or T5 lighting systems that provide a balanced spectrum work well.
Water Flow: Moderate water flow is ideal to ensure adequate nutrient exchange without causing polyp retraction or tissue damage.
Placement: Position this coral on stable rockwork in the mid to lower regions of the aquarium, allowing enough space to prevent aggression with neighbouring corals. Caulastrea echinulata requires spacing to avoid contact with faster-growing or aggressive species.
Care Level: Suitable for intermediate to advanced hobbyists due to its moderate care requirements and sensitivity to water quality fluctuations.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from occasional feeding of small meaty foods such as phytoplankton, marine snow, or specialised coral foods to promote growth and vibrancy.
Reef Compatibility: Yes, with adequate spacing from other corals to prevent stinging or overgrowth.
Origin: Not Provided.
Maximum Size: Colonies can grow significantly over time; individual polyps typically reach up to 2 cm in diameter.
Minimum Tank Size: A minimum of 75 litres (20 gallons) is recommended to provide stable water parameters and adequate space.
Regular monitoring of water parameters, including calcium, alkalinity, and magnesium, is essential to maintain coral health. Avoid rapid changes in lighting or flow to prevent stress.
