Overview
The Symphyllia Rainbow Rim from Indonesia is a standout variant of the classic brain coral, distinguished by its glowing multicolour edge that encircles a darker, more subdued core. This striking rim creates a "halo" effect under actinic lighting, making the coral visually explode with colour when viewed from above. Its fleshy lobes and meandering ridges give it texture and movement, making it an impressive display coral in any LPS-dominant reef.
Highly desired for its vibrant perimeter contrast and relative ease of care, this coral is a premium choice for reefers looking to add sophistication and colour variety to their tank.
Care & Feeding
Photosynthetic but benefits significantly from target feeding. Offer small meaty foods (e.g., mysis shrimp, reef roids, chopped clam) once or twice per week to encourage robust tissue growth and colour saturation.
Optimal Parameters
Alkalinity (dKH): 8–11
Calcium (Ca): 420–460 ppm
Magnesium (Mg): 1300–1400 ppm
Nitrate (NO3): 2–10 ppm
Phosphate (PO4): 0.01–0.05 ppm
Placement
Place this coral on the substrate or a wide, stable ledge. Ensure low to moderate flow to prevent tissue recession, and leave room from aggressive neighbours due to potential for nighttime sweeper tentacles.
🌟🌈 Halo of Colour – With its neon rim and dynamic ridged surface, the Symphyllia Rainbow Rim brings refined colour and structure to your reef. Ideal for those seeking contrast and movement in a mature aquascape.
