Euphyllia cristata (Joker) is a captivating large polyp stony (LPS) coral prized for its unique, flowing tentacles and striking appearance. This tiny Tank-Bred specimen offers marine aquarists an opportunity to introduce a dynamic and visually engaging coral to their reef tanks.
Lighting Requirements: Moderate to high lighting is recommended to maintain vibrant coloration and healthy growth. LED or T5 lighting systems with a PAR range of 100-250 are suitable.
Water Flow: Moderate, indirect water flow is ideal to gently sway the tentacles without causing tissue damage. Avoid strong direct currents that may stress the coral.
Placement: Position this coral in the middle to lower regions of the aquarium where it can receive adequate light and flow. Ensure sufficient spacing from neighbouring corals to prevent aggressive interactions, as Euphyllia species possess sweeper tentacles.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from occasional feeding of meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods to support growth and colour.
Reef Compatibility: Yes, with adequate spacing. Euphyllia cristata can exhibit territorial behaviour; maintain a minimum distance of 10-15 cm from other corals to avoid stinging.
Care Level: Moderate. Suitable for aquarists with some experience in LPS coral husbandry.
Origin: Not Provided.
Maximum Size: Typically grows up to 20 cm per head in mature specimens.
Minimum Tank Size: Recommended 75 litres or larger to provide stable water parameters and space for growth.
Regular water testing and stable marine conditions are essential for the health of Euphyllia cristata. Maintain temperature between 24-27°C, salinity at 1.023-1.025 SG, and stable pH around 8.1-8.4.
