Euphyllia ancora, commonly known as the Hammer Coral, is a popular large polyp stony (LPS) coral prized for its unique hammer-shaped tentacles and vibrant orange-yellow colouring. This medium-sized specimen adds dynamic movement and colour to mature reef aquariums.
Lighting: Euphyllia ancora thrives under moderate lighting conditions. LED or T5 lighting systems providing moderate PAR levels are ideal to maintain its vivid pigmentation without causing stress.
Water Flow: Moderate, indirect water flow is recommended to gently sway the tentacles and prevent detritus accumulation, while avoiding strong currents that can damage the delicate polyps.
Placement: Position this coral in the middle to lower regions of the tank, ensuring adequate space around it to prevent aggressive sweeper tentacles from harming neighbouring corals. A minimum spacing of 10-15 cm is advised.
Care Level: Suitable for intermediate to advanced hobbyists due to its moderate care requirements and sensitivity to water quality fluctuations.
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.
Compatibility: Reef safe with caution; ensure adequate spacing from other corals to avoid aggression. Not suitable for tanks with aggressive coral species or large, coral-nipping fish.
Origin: Not Provided.
Maximum Size: Typically reaches up to 30 cm in diameter under optimal conditions.
Minimum Tank Size: Recommended for tanks of 100 litres or larger to provide stable water parameters and sufficient space.
