Physogyra lichtensteini, commonly known as Bubble Coral, is a captivating large polyp stony (LPS) coral from the family Euphyllidae. This small specimen features distinctive inflated vesicles that expand and contract, creating a dynamic and attractive display in reef tanks.
Lighting Requirements: Moderate lighting is ideal for Physogyra lichtensteini. Too intense lighting can cause bleaching, while too little light may inhibit growth. LED or T5 lighting systems with adjustable intensity work well.
Water Flow: Gentle to moderate water flow is recommended. Strong currents can damage the delicate vesicles, so positioning in a low-flow area of the aquarium is best.
Placement and Spacing: Place this coral on a stable substrate or rockwork where it can fully expand without obstruction. Allow adequate spacing from neighbouring corals to prevent aggressive interactions, as Physogyra lichtensteini can extend sweeper tentacles.
Diet: While primarily photosynthetic via symbiotic zooxanthellae, this coral benefits from supplemental feeding. Offer small meaty foods such as mysis shrimp or specialised coral foods 1-2 times per week to promote health and growth.
Reef Compatibility: Reef safe with caution. It is generally compatible with other peaceful corals and reef inhabitants but requires space to avoid stinging neighbours.
Care Level: Moderate. Suitable for hobbyists with some experience in LPS coral husbandry.
Origin: Not Provided.
Maximum Size: Typically up to 30cm in diameter under optimal conditions.
Minimum Tank Size: 90 litres (approximately 24 US gallons) recommended to provide stable water parameters and adequate space.
