The Goniopora spp. (Green-Blue Centre) is a captivating large polyp stony (LPS) coral prized for its delicate, flower-like polyps that display vibrant green tentacles surrounding a striking blue centre. This tiny, tank-bred specimen is perfect for marine aquarists looking to add a splash of colour and movement to their reef aquarium.
Care Level: Moderate. Goniopora corals require stable water parameters and consistent care to thrive.
Lighting: Moderate lighting is recommended, such as T5 fluorescents or LED systems with medium PAR levels. Avoid intense direct light to prevent bleaching.
Water Flow: Moderate, indirect water flow is ideal. Too strong a current can cause the polyps to retract, while too little flow may lead to detritus accumulation.
Placement: Position this coral on a stable rockwork base with enough space to allow full polyp extension without contact with neighbouring corals. Adequate spacing minimises aggression and tissue damage.
Diet: While Goniopora spp. benefit from photosynthesis via their symbiotic zooxanthellae, supplemental feeding with planktonic foods such as phytoplankton, rotifers, or specialised coral foods 2-3 times weekly supports optimal growth and polyp extension.
Reef Compatibility: Yes, with adequate spacing. This coral is generally peaceful but can extend sweeper tentacles that may sting nearby corals.
Origin: Not Provided. As a tank-bred coral, it is sustainably propagated in captivity.
Maximum Size: Not Provided. Goniopora spp. typically grow slowly and can reach moderate colony sizes over time.
Minimum Tank Size: 75 litres (20 gallons) recommended to maintain stable water conditions.
Regular water testing and maintenance are essential to keep parameters within optimal ranges: temperature 24-27°C, salinity 1.023-1.025, calcium 400-450 ppm, alkalinity 8-12 dKH, and magnesium 1250-1350 ppm.
