Euphyllia glabrescens, commonly known as the Rapunzel Holy Grail coral, is a spectacular large polyp stony (LPS) coral prized for its long, elegant tentacles that sway gracefully in the aquarium current. This large specimen is perfect for experienced hobbyists looking to add dynamic movement and vibrant colour to their reef tanks.
Lighting: Moderate to high lighting is recommended to maintain optimal health and vibrant coloration. LED or T5 lighting systems that provide a balanced spectrum work well.
Water Flow: Euphyllia glabrescens thrives under moderate, indirect water flow. Strong currents can cause the delicate tentacles to retract or sustain damage, so positioning away from direct powerheads is advised.
Placement: Place this coral in the middle to lower regions of the tank where it has ample space to extend its tentacles without touching neighbouring corals. Adequate spacing is essential to prevent aggressive interactions, as Euphyllia species can exhibit sweeper tentacle behaviour.
Care Level: Moderate care level; suitable for aquarists with some experience in maintaining LPS corals.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from occasional feeding of meaty foods such as brine shrimp, mysis shrimp, or specialised coral foods to promote growth and colour.
Reef Compatibility: Yes, with adequate spacing to avoid coral warfare.
Minimum Tank Size: 90 litres (approximately 20 gallons) to provide sufficient space and stable water parameters.
Origin: Not Provided.
Maximum Size: Can reach up to 30 cm in diameter under optimal conditions.
