Physogyra lichtensteini, commonly known as the Green Bubble Coral, is a captivating large polyp stony (LPS) coral prized for its distinctive bubble-like vesicles and vibrant green hues. This XXL specimen offers an impressive display, making it a standout feature in mature reef tanks.
Care Level: Moderate to advanced. Requires stable water parameters and attentive husbandry.
Lighting: Moderate lighting is recommended, ideally provided by LED or T5 fixtures. Avoid intense direct light to prevent bleaching; acclimate slowly to your tank’s lighting conditions.
Water Flow: Low to moderate, indirect water movement is best to ensure the coral’s delicate polyps are not damaged while facilitating gas exchange and nutrient delivery.
Placement: Position on a stable substrate or rockwork in the lower to middle sections of the aquarium. Ensure ample space around the coral to prevent aggression or stinging from neighbouring corals, as Physogyra lichtensteini can extend sweeper tentacles.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from supplemental feeding of meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods 1-2 times per week.
Reef Compatibility: Yes, with adequate spacing. This coral can coexist with other peaceful LPS and SPS corals if given sufficient room to expand.
Minimum Tank Size: 90 litres (approx. 20 gallons) or larger to maintain stable water conditions and accommodate growth.
Origin: Not Provided.
Maximum Size: Can reach up to 30 cm in diameter under optimal conditions.
Regular monitoring of water parameters, including calcium, alkalinity, and magnesium, is essential to support skeletal growth. Maintain stable temperature (24-26°C), salinity (1.023-1.025), and low nutrient levels for optimal health.
