Description
Symphyllia (often reclassified as Australophyllia) are relatively easy-to-care-for LPS corals requiring stable, clean water, low-to-moderate lighting, and gentle-to-moderate flow. They are semi-aggressive, needing space for sweeper tentacles. Feed them meaty foods for optimal growth.
Key Care Parameters
Lighting: Low to moderate is ideal. High light can cause bleaching, so place them lower in the tank.
Flow: Moderate flow is best to keep detritus from settling on the coral and causing tissue damage.
Water Quality: Stable parameters are essential.
Temperature 74-78°F
Salinity 1.024-1.026
pH 8.1-8.4
Alkalinity 8-12 dKH
Calcium 400-450 ppm
Magnesium 1250-1350 ppm.
Feeding: While photosynthetic, regular target feeding with meaty foods like mysis shrimp, krill, or plankton helps them thrive and grow faster.
Placement: Place on the sandbed or low on rockwork, leaving plenty of room for sweeper tentacles that may extend at night.
Potential Issues
Tissue Recession: Often caused by too much light, too much flow, or unstable water chemistry.
