Goniastrea spp. are a genus of large polyp stony (LPS) corals belonging to the family Faviidae. Known for their distinctive, tightly packed corallites and vibrant colours, these corals add impressive texture and depth to mature reef aquariums.
Care Level: Moderate to advanced. Goniastrea spp. require stable water parameters and consistent care to thrive.
Lighting Requirements: Moderate lighting is recommended. They perform well under LED or T5 lighting systems that provide a balanced spectrum without excessive intensity.
Water Flow: Moderate, indirect water flow is ideal. Too strong a current can cause tissue damage, while too little flow may lead to detritus accumulation.
Placement: Position in the lower to middle regions of the tank to avoid direct intense light and strong currents. Ensure adequate spacing from neighbouring corals to prevent aggressive interactions.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefit from supplemental feeding of meaty foods such as phytoplankton, marine snow, or specialised coral foods.
Reef Compatibility: Yes, with adequate spacing. Goniastrea spp. can exhibit moderate aggression through sweeper tentacles, so maintain sufficient distance from other corals.
Origin: Not Provided.
Maximum Size: Not Provided; colonies can grow substantially over time under optimal conditions.
Minimum Tank Size: Not Provided; however, a mature reef tank of at least 100 litres is advisable to accommodate growth and maintain stable water quality.
Regular monitoring of water parameters, including calcium, alkalinity, and magnesium, is essential to support skeletal growth. Maintain stable temperature and salinity levels to reduce stress.
