Euphyllia cristata (NYknicks) is a medium-sized large polyp stony (LPS) coral prized for its distinctive, elongated tentacles and intricate skeletal structure. This coral adds dynamic movement and texture to reef aquariums, making it a popular choice among enthusiasts.
Care Level: Moderate – suitable for intermediate hobbyists with some experience in maintaining stable reef conditions.
Lighting Requirements: Euphyllia cristata thrives under moderate to high lighting. LED, T5, or metal halide lighting systems are recommended to support its photosynthetic needs.
Water Flow: Moderate, indirect water flow is ideal. Strong currents can cause tissue damage, while too little flow may lead to detritus accumulation.
Placement: Position this coral in a location with adequate space to prevent tentacle contact with neighbouring corals, as Euphyllia species can exhibit aggressive behaviour through sweeper tentacles. Mid to lower areas of the tank are often preferred.
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 vibrancy.
Reef Compatibility: Yes, with adequate spacing to avoid aggression towards other corals.
Minimum Tank Size: 75 litres (20 gallons) to ensure stable water parameters and sufficient space.
Origin: Not Provided.
Maximum Size: Typically grows up to 15 cm (6 inches) in diameter under optimal conditions.
