Euphyllia glabrescens (Blueberry) is a popular large polyp stony (LPS) coral prized for its elegant, elongated tentacles tipped with a vivid blue hue, resembling blueberries. This coral adds both movement and colour to reef aquariums, making it a favourite among hobbyists seeking a visually dynamic display.
Care Level: Moderate – suitable for aquarists with some experience in LPS coral husbandry.
Lighting Requirements: Euphyllia glabrescens thrives under moderate lighting conditions. LED or T5 lighting systems providing a PAR range of approximately 100-150 are ideal to maintain vibrant colouration without causing bleaching.
Water Flow: Moderate, indirect water flow is recommended. Strong currents can cause the delicate tentacles to retract or sustain damage, while too little flow may lead to detritus accumulation and poor health.
Placement: Position this coral in the middle to lower regions of the aquarium where it can extend its tentacles freely without touching neighbouring corals. Adequate spacing is essential to prevent aggressive interactions, as Euphyllia species possess sweeper tentacles that can sting adjacent corals.
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 polyp extension.
Reef Compatibility: Yes, with adequate spacing. Euphyllia glabrescens can coexist with many reef-safe fish and invertebrates but requires careful placement to avoid coral warfare.
Minimum Tank Size: 90 litres (approximately 20 gallons) to provide stable water parameters and sufficient space for growth.
Origin: Not Provided.
Maximum Size: Typically grows up to 30 cm per head under optimal conditions.
Regular monitoring of water parameters including calcium, alkalinity, and magnesium is advised to support skeletal growth. Maintain stable temperature (24-26°C), salinity (1.023-1.025 SG), and low nutrient levels for best results.
