Euphyllia divisa (Green) is a popular large polyp stony (LPS) coral known for its distinctive, flowing green tentacles that create a captivating display in any reef aquarium. This medium to large specimen offers excellent visual impact and movement, making it a prized addition for marine aquarists seeking vibrant and dynamic corals.
Care Level: Moderate – suitable for hobbyists with some experience in LPS coral husbandry.
Lighting: Euphyllia divisa thrives under moderate lighting conditions. LED, T5, or metal halide lighting systems providing moderate PAR levels are ideal to maintain healthy growth and vibrant colouration.
Water Flow: Moderate, indirect water flow is recommended to gently sway the tentacles without causing tissue damage. Avoid strong direct currents which can stress the coral.
Placement: Position this coral in the middle to lower regions of the tank where it can extend its tentacles freely without touching neighbouring corals. Adequate spacing is essential to prevent aggressive interactions, as Euphyllia divisa can exhibit sweeper tentacle behaviour.
Diet: Primarily photosynthetic through symbiotic zooxanthellae, but benefits from occasional feeding of meaty foods such as brine shrimp, mysis shrimp, or specialised coral foods to promote growth and health.
Reef Compatibility: Yes, with adequate spacing. This coral can be aggressive towards nearby corals due to sweeper tentacles, so ensure sufficient distance to avoid damage.
Minimum Tank Size: 90 litres (approximately 20 gallons) to provide stable water parameters and space for growth.
Origin: Not Provided.
Maximum Size: Euphyllia divisa can reach up to 30 cm (12 inches) in diameter under optimal conditions.
Regular water quality monitoring and stable parameters are essential for maintaining Euphyllia divisa. Maintain temperature between 24-27°C, salinity at 1.023-1.025 SG, and stable alkalinity and calcium levels to support skeletal growth.
