Blastomussa merletti is a captivating large polyp stony (LPS) coral prized for its fleshy, colourful polyps and robust growth. This XXXL specimen offers a dramatic visual impact, making it a standout addition to mature reef tanks.
Care Level: Moderate to advanced. Requires stable water parameters and attentive husbandry.
Lighting: Moderate lighting is preferred. Too intense light may cause bleaching, so LED or T5 lighting with adjustable intensity is ideal.
Water Flow: Low to moderate water flow encourages polyp extension without causing tissue damage.
Placement: Position on the substrate or lower rockwork with adequate space around it to prevent aggression towards neighbouring corals. Maintain at least 10cm distance from other LPS corals.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from supplemental feeding of meaty foods such as mysis shrimp or specialised coral foods 1-2 times per week.
Reef Compatibility: Yes, with adequate spacing due to its potential to extend sweeper tentacles.
Origin: Not Provided.
Maximum Size: Polyps can reach up to 5cm in diameter; colony size depends on growth conditions.
Minimum Tank Size: 90 litres (approximately 20 gallons) recommended to maintain stable water quality.
Regular monitoring of calcium, alkalinity, and magnesium is essential to support skeletal growth. Avoid rapid changes in water parameters to reduce stress.
