Euphyllia glabrescens (Green) Ultra XXL is a spectacular large polyp stony (LPS) coral prized for its long, flowing tentacles and vivid green coloration. Commonly known as the Torch Coral, this specimen is an Extra Extra Large (XXL) variant, perfect for experienced marine aquarists looking to add impressive movement and colour to a mature reef tank.
Lighting: Moderate to high lighting is recommended to maintain vibrant colour and healthy growth. LED, T5, or metal halide lighting systems are suitable, with acclimation advised to prevent bleaching.
Water Flow: Moderate, indirect water flow is ideal. Strong direct currents can cause tentacle damage, while too little flow may lead to detritus accumulation and poor health.
Placement: Position this coral in the middle to lower regions of the aquarium where it has ample space to extend its tentacles without touching neighbouring corals. Adequate spacing is essential to prevent aggression and stinging interactions.
Care Level: Moderate. This coral requires stable water parameters and consistent maintenance but is suitable for aquarists with some reef-keeping experience.
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.
Compatibility: Reef safe with caution. Euphyllia glabrescens has long sweeper tentacles that can sting neighbouring corals, so maintain adequate spacing to avoid damage.
Origin: Not Provided.
Maximum Size: Can reach up to 30 cm (12 inches) in polyp length under optimal conditions.
Minimum Tank Size: Recommended for tanks 120 litres (30 gallons) or larger to accommodate its size and water quality needs.
Regular monitoring of water parameters, including calcium, alkalinity, and magnesium, is essential to support skeletal growth. Maintain stable temperature (24-27°C), salinity (1.023-1.025 SG), and low nutrient levels for best results.
