Product Description
Purple Torch Coral (Euphyllia glabrescens) is a popular, aggressive Large Polyp Stony (LPS) coral known for its vibrant colors (purple, pink, green) and flowing tentacles, requiring moderate lighting, strong indirect flow, stable parameters (calcium, alkalinity, magnesium), and significant space due to potent sweeper tentacles that sting other corals. They benefit from targeted feeding but primarily get energy from light, thriving in established reef tanks with proper water chemistry and placement away from neighbors.
Key Characteristics & Needs:
Type: LPS Coral (Euphyllia genus).
Appearance: Fleshy polyps with rounded tips, often purple with green or pink/white tips, swaying in the current.
Temperament: Aggressive; has long sweeper tentacles that sting other corals, so give it space.
Lighting: Moderate, indirect light (around 100-125 PAR).
Water Flow: Moderate to strong, indirect, and turbulent to keep tentacles moving and clean.
Water Parameters (Stable is Key):
Temp: 75-78°F (24-26°C).
Salinity: 1.024-1.026 SG.
pH: 8.1-8.4.
Alk: 8-12 dKH.
Ca: 400-450 ppm.
Mg: 1300-1500 ppm (higher can be beneficial).
Feeding: Benefits from weekly targeted feeding (pellets, micro-plankton), but photosynthesis provides most energy.
Care Tips:
Placement: Middle of the tank on rocks, with ample space from other corals.
Acclimation: Gradually introduce to new lighting to prevent shock.
Signs of Health: Full polyp extension during the day, swaying in flow; brown stringy bits before splitting (normal).
Signs of Stress: Retraction, dull color, tissue loss (may need treatment).
Benefits: Adds natural movement and color; aquacultured varieties are common.
