Symphyllia spp.
An LPS coral with complex brain-like patterns. Vivid fluorescent green and red specimens are popular.
Symphyllia is a genus of large-polyp stony corals (family Lobophylliidae) forming massive brain-like colonies on Indo-Pacific reefs. Their deeply convoluted ridges and valleys can span 20–50 cm or more in diameter, displaying vivid fluorescence in green, red, orange, and purple. Moderate lighting (100–200 PAR) and gentle indirect flow are ideal; strong direct current damages the fleshy tissue. Extended sweeper tentacles emerge nightly and aggressively sting neighboring corals, so a minimum 15 cm clearance from other specimens is advised. Weekly target feeding with brine shrimp or small pellets accelerates growth and enhances color. Fragging is straightforward using a band saw or chisel. Symphyllia's dramatic size and striking coloration make it a showpiece in large reef aquaria.
The Symphyllia lives 10+ years.
The Symphyllia grows to 10-30cm.
The ideal water temperature for the Symphyllia is 24〜27℃.
Stable water parameters (24–27°C, KH 8–10) are essential.

Moderate lighting (100-200 PAR) is ideal. Strong light is unnecessary; place it mid-tank under steady light.
Give it low to moderate indirect flow and avoid direct strong current that damages the polyps. It extends long sweeper tentacles at night, so keep at least 15 cm from other corals.
Keeping 24-27C and KH 8-10 stable is important. It is an LPS that grows large, so hold parameters steady over the long term.
Feeding brine shrimp or small pellets once or twice a week promotes growth. It is easiest to feed at night when the tentacles are extended.
