Euphyllia glabrescens (Holy Grail) (p/h) | T

Euphyllia glabrescens, commonly known as the Holy Grail coral, is a prized large polyp stony (LPS) coral admired for its elegant, long, and flowing tentacles that sway gracefully in the aquarium current. This tiny Tank-Bred specimen is perfect for hobbyists looking to add movement and texture to their reef tanks.

Care Level: Moderate. This coral requires stable water parameters and consistent care but is suitable for aquarists with some experience in LPS coral husbandry.

Lighting Requirements: Moderate lighting is ideal, such as LED or T5 fixtures providing a PAR range of approximately 100-150. Avoid intense direct light to prevent bleaching.

Water Flow: Moderate, indirect water flow is best to ensure the tentacles gently sway without being damaged by strong currents.

Placement: Position in the middle to lower regions of the tank where lighting and flow conditions are optimal. Ensure adequate spacing from neighbouring corals to prevent aggressive interactions, as Euphyllia glabrescens has sweeper tentacles that can sting nearby corals.

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.

Reef Compatibility: Yes, with adequate spacing. This coral can be aggressive towards other corals due to its sweeper tentacles, so maintain sufficient distance to avoid damage.

Minimum Tank Size: 90 litres (approximately 24 gallons) to provide stable water conditions and space for growth.

Origin: Tank-Bred in controlled aquaculture facilities, ensuring sustainability and reduced impact on wild populations.

Maximum Size: Colonies can grow up to 30 cm (12 inches) across in mature specimens, with individual polyps extending several centimetres.

Adding Euphyllia glabrescens (Holy Grail) to your reef aquarium brings dynamic movement and a striking visual appeal. With proper care and placement, this coral will thrive and become a captivating centrepiece in your marine setup.
