Euphyllia glabrescens (Holy Grail) | XL

Euphyllia glabrescens, commonly called the Holy Grail coral, is a spectacular large polyp stony (LPS) coral known for its long, flowing tentacles and captivating movement in the aquarium. This Extra Large specimen offers a bold visual impact, making it a prized choice for advanced marine aquarists.

Lighting: Moderate to high lighting is recommended, ideally provided by LED or T5 fixtures that support coral growth without causing bleaching. Avoid sudden intense light exposure to prevent stress.

Water Flow: Moderate, indirect water flow is best to gently sway the tentacles without causing damage. Strong direct currents can harm the delicate polyps.

Placement: Position this coral in the middle to lower regions of the reef tank, ensuring ample space from neighbouring corals to prevent aggressive sweeper tentacle contact. Spacing of at least 10cm is advised.

Compatibility: Reef safe with caution; Euphyllia glabrescens can extend sweeper tentacles at night that may sting nearby corals. Maintain adequate spacing to avoid conflicts.

Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from occasional feeding of meaty foods such as brine shrimp or specialised coral foods to promote growth and vibrancy.

Tank Requirements: A minimum tank size of 90 litres is recommended to provide stable water parameters and space for growth.

Water Parameters: Maintain stable marine conditions with temperature 24-27°C, salinity 1.023-1.025, pH 8.1-8.4, and low nutrient levels.

This Extra Large Holy Grail coral is a stunning centerpiece for mature reef aquariums, offering dynamic movement and colour that enhances any marine display.
