Euphyllia cristata (Green) Ultra is a stunning large polyp stony (LPS) coral prized for its unique, vibrant green tentacles and distinctive ultra morph. This extra large specimen makes a bold statement in mature reef aquariums, offering both beauty and movement with its gently swaying polyps.
Lighting: Moderate to high lighting is recommended to maintain vibrant coloration and healthy growth. LED or T5 lighting systems that provide a balanced spectrum work well.
Water Flow: Moderate, indirect water flow is ideal to ensure the delicate polyps are gently moved without being damaged by strong currents.
Placement: Position this coral in the middle to lower regions of the tank where it can expand fully without touching neighbouring corals. Adequate spacing is essential to prevent aggressive interactions, as Euphyllia species can extend sweeper tentacles.
Care Level: Suitable for intermediate to advanced hobbyists due to its size and sensitivity to water quality fluctuations. Maintain stable parameters with regular water changes and monitoring.
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.
Reef Compatibility: Yes, with adequate spacing from other corals to avoid aggression.
Minimum Tank Size: A minimum of 120 litres (30 gallons) is recommended to accommodate its size and provide stable water conditions.
Origin: Not Provided.
Maximum Size: Can reach up to 30 cm (12 inches) in diameter when fully grown.
